    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.

    Smith Predictor control is theoretically a good solution to the problem of controlling the time delay systems. However, it seldom gets use because it is almost impossible to find out a precise mathematical model of the practical system and very sensitive to uncertain system with variable time-delay. In this paper is concerned, with a design method, of smith predictor for temperature control system by Coefficient Diagram Method (CDM). The simulation results show that the control system with smith predictor design by CDM is stable and robust whilst giving the desired time domain system performance. © ICROS.

    The authors present optimization parameters of rotary positioner controller in hard disk drive servo track writing process using coefficient diagram method; CDM. Due to estimation parameters in PI Positioning Control System by expected ratio method cannot meet the required specification of response effectively, we suggest coefficient diagram method for defining controller parameters under the requirement of the system. Finally, the simulation results show that our proposed method can improve the problem in tuning parameter of rotary positioner controller. It is satisfied specification of performance of control system. Furthermore, it is very convenient as a fast adjustment damping ratio as well as a high speed response.
