This paper presents the approach to design PID controller for a modified quadruple-tank process using inverted decoupling technique. In case of non-minimum phase, TITO system, such as modified quadruple-tank process which can't be controlled by PID controller with standard decoupling technique because the system can't be stabled by saturating manipulate signal. With the proposed method, The inverted decoupling controllers, decreasing the cross coupling between inputs and outputs, transform TITO plant transfer function model into SISO form so that SISO controller for each SISO model can be designed by Root Locus Technique easily and efficiently. PID controller with inverted decoupling can stabilize an unstable non-minimum-phase system and minimize several undesirable influences from an interaction in TITO process. The results from control system design can be illustrated by the experiments. © 2011 ICROS.

Optimized water management strategies are among the most crucial concerns in a biomass power plant. Especially during the times of water scarcity, an improper water supply planning and operation result in a detrimental power generation or shut down processes. This paper aims to propose the cyber-physical cloud computing (CPCC), a mechanism of analysis and control physical process using cloud-based framework, in order to improve the efficiency of water management system in a biomass power plant. In this study, a 9.9 MW biomass power plant is implemented to investigate the performance of CPCC. The architecture of the proposed system consists of three physical tiers. The first tier is a tier of physical devices included with pressure, flow, pH sensors, water pumps and valves that are responsible for detecting the physical data and interacting with the water production process. The second tier is an edge computing device which functions as a controller, embedded server, data storage, gateway and switch to manage all operational tasks in an intranet area. The third tier is a cloud computing system which enables big data applications such as online monitoring and visualization of process operation, adaptive filtration fouling control, consuming water and total water cost analysis. The results validate the effectiveness of the proposed system as the ability of an adaptive fouling control system to adjust backwash scheduling and chemical dosing so that achieving the target of purified water quality even during the fluctuation of raw water qualities. Subsequently, the water treatment system can achieve the capability for optimal total water cost operations under a target permeate flow rate and the percent of the recovery. Significantly, the data analytics in the CPCC reflect current operational requirements of water under local climate conditions, likewise contribute to the practical solution for sustainable water resource planning in the energy production.

This paper presents the design of PI controller using Decoupling and CRA technique for quadruple-tanks process. In case of, TITO interacting system such as quadruple-tanks process, the controller designs have been performed ambitiously because interferences between inputs and outputs. With the proposed method, The Decoupling controllers have been used for decreasing the cross coupling between inputs and outputs and transforming TITO plant transfer function into SISO form so that SISO controller for each SISO model can be designed easily and efficiently. Furthermore, Using CRA technique has made the output response achieve the required performance specification. Also, in non-minimum-phase, PI controller with inverted Decoupling can stabilize the system and minimize several undesirable influences from an interaction in TITO process. The results from control system design can be illustrated by the experiments. © 2011 ICROS.

This paper presents the design of PID controller for track following control of hard disk drive using Coefficient Diagram Method (CDM). For this reason, Track following control of hard disk drive process has many disturbances from internal and external sources, so determining satisfactory controller parameters to stabilize control system and satisfying response specification is difficult. The proposed PID controller design using Coefficient Diagram Method (CDM) based on proper choosing the coefficients of the characteristic transfer function of the closed loop control system in accordance with stability index and equivalent time constant is applying an uncomplicated and convenience technique to controller design of Track following control in hard disk drive process. Matlab simulation results shown that CDM design is fairly stable and robust whilst giving the convenience in controller's parameters adjustment. © 2011 ICROS.

A control system design with Coefficient Diagram Method (COM) is proven that effective for SISO control design. But the control system design for TITO via COM is not concrete procedure. In this paper presents the control system design method for quadruple-tank process via CDM. By using the decentralized method for both non-minimum phase and minimum phase are made. The results from Integral-Proportional (I-P) controller's design via CDM and standard Proportional-Integral (PI) controls are also shown to compare the merits of the proposed controllers.

The author presents following control of the hard disk drive using derivative state constrained optimal 2 H controls (H<inf>2</inf>ẋ). The study in this paper concern to the control amount of NRPE (non repeatable position error) and PES (position error signal) of track following control in the hard disk drive process by the effective method. The derivative state constrained optimal H<inf>2</inf> control (H<inf>2</inf>ẋ) has been formulated to suppress the rate of changes of state variables. It is suitable for the oscillated system and able to be used in non linear system. Thus, the derivative state constrained optimal H<inf>2</inf> control (H<inf>2</inf>ẋ) has been applied to track following control in the hard disk drive for increasing the accuracy of head positioning by decreasing the effect from oscillation, variation and non linearity characteristic in its system. Finally, the simulation results show that our proposed method can satisfy the design specifications of track following servo control system effectively. ©ICROS.

This paper presents an adaptive fractional order PIλDμ control for multi-configuration tank process (MCTP) toolbox which aims at demonstrating the problem of reference tracking and cross coupling rejection in multi-input-multi-output system. Moreover, we investigate the cases where the system is in the mode of minimum phase and non-minimum phase configuration. Besides providing theoretical control system analysis and design, we develop the multi-configuration tank process software toolbox for providing the non-linear functions of dynamic models of multi-configuration tank process which is the advantage tool for investigating the performances of the controllers. The software toolbox is developed from discrete state P-file S-function which is operated within the MATLAB environment for providing many non-linear functions of dynamic models of multi-configuration tank process such as multi-input multi-output quadruple tank full-interacting process, multi-input multi-output quadruple tank process, multi-input single-output triple tank interacting process, multi-input multi-output coupled tank interacting process. All actual process attributes are encapsulated in S-function as the input parameters, thus the multi-tank function block can be simply adjusted by specifying the physical properties of the tank system. The study explains about the mathematical model of multi-configuration tank process, nonlinear dynamic characteristic, minimum phase and non-minimum phase configuration, software toolbox features and also describes the design of the adaptive fractional order PIλDμ controller including the performance validation. The results have been illustrated that the proposed controller design scheme can provide the sufficient effectiveness in the performance, stability and robustness. Furthermore, these tests reinforce the usefulness of MCTP toolbox as a complete simulation tool for users to perform an engineering research of multi-configuration tank control system analysis and design, moreover, it contains very useful for validating the control algorithm of multi-input-multi-output system.
