Item type:Publication, New fine adjustment technique for heating process(2000-01-01) ;Tipsuwanporn, V. ;Jamjan, K. ;Piyarat, W.; Tarasantisukand, C.This paper proposes controlling of temperature in an oven by using Integral - Cycle Binary Rate Modulation (ICBRM method and ac line with frequency 50 Hz, Microcontroller MCS-51 controls Binary Rate Multiplier ( B M according to Proportional Integral controller (Po function . Discrete signals are used in the system modeled by using Ziegler Nichols principle for analyzing the stability before designing the system. This procedure makes it easy to investigate system response. The system is implemented by 8 bits digital circuit which gives 1024 patterns of ac signal for controlling the generation of energy for 3,000 watts thermal coil every 20 ms of each cycle. We divide scan time (Tsn) in to 4 intervals, 5 ms interval is selected to generate 256 patterns ICBM. Because of this method gives the ripple lower than 2% it generates less noise for system. Moreover, we can consider whole system from the time model of control procedure and ICBM algorithm40-200 OC with f I OC error in the I cubic meter oven. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, New design technique of controlling 2 quadrant DC motor drive(2000-01-01) ;Piyarat, W. ;Paraken, Y. ;Tipsuwanporn, V. ;Sawangsinkasikit, W.This paper proposes a control technique for DC motors which can determine the time response of speed, under both no load and on load conditions, in less than 2 seconds. It is operated by an 8-bit binary rate multiplier (BRM) under the PI control process. The motor under test is a two-quadrant type. The BRM 8-bit are generated from 8 principle waveforms by linear combination; finally 256 waves are attained. These waveforms are sent to control the motor with the required speed. It is known that BRM give low ripple-less than 1%-and, hence, less noise disturbance to the system. These BRM can be applied to reverse motor direction with fast response or sudden stop. Energy fed to the motor is also low but gives high efficiency. - Some of the metrics are blocked by yourconsent settings

Item type:Publication, Multi level contract net protocol based on holonic manufacturing system implement to industrial networks(2004-12-01); ;Tipsuwanporn, V.; ;Rerngreun, P.This paper presents a flexible manufacturing system (FMS) that cooperated the holonic manufacturing system (HMS) with automatic material handling devices via industrial networks. The HMS is described as an intelligent manufacturing system that employs multi-agent system with negotiation protocols. The traditional HMS's negotiation protocol usually used the contract net protocol (CPN) and multi-level contract net protocol (MCPN). This paper develops a cooperative system that applies the concept of HMS to implement a distributed control system for automatic warehouse and FMS. Results from simulation indicated that our approach is able to improve the overall system flexibility. The system is able to reconfigure the re-order points, increase the system fault tolerances, and provides the dynamic rescheduling. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, A recognition system for stamped number on non-smooth metallic surface(2009-01-01)This paper deals with the application of moments for recognizing of stamped number on metallic surface which contains the stamped number. It is a complicated task to be read automatically. Recently, the method of modeling and analyzing 3D surface data using a laser-scanning instrument has been presented. The advantage of the combined moment method is that it is able to eliminate some of the problem associated with the Gibbs phenomena[1][2]. This method is also applied to real-time modeling of 3D surface encountered to separate the global geometry from periodic undulations and local anomalies. Afterwards, the image of numbers on the steel block is clear enough to perform numbers recognition. In this paper, pattern recognition based on moment function such as Hu's moment invariants, Zernike moments, and Orthogonal Fourier Mellin Moments is used to recognize the stamped number after analyzing 3D surface data of the steel block. The results of classification rate are satisfactory, and it is possible to implement in an industrial environment. - Some of the metrics are blocked by yourconsent settings
