Repetitive control for the track-following servo system of an optical disk drive
Disturbances acting on the track-following servo system of an optical disk drive inherently contain significant periodic components that cause tracking errors of a periodic nature. Such disturbances can be effectively rejected by employing a repetitive controller, which must be implemented carefully in consideration of system stability. Plant uncertainty makes it difficult to design a repetitiv...
متن کاملHybrid Robust Control Law with Disturbance Observer for High-Frequency Response Electro-Hydraulic Servo Loading System
Abstract: Addressing the simulating issue of the helicopter-manipulating booster aerodynamic load with high-frequency dynamic load superimposed on a large static load, this paper studies the design of the robust controller for the electro-hydraulic loading system to realize the simulation of this kind of load. Firstly, the equivalent linear model of the electro-hydraulic loading system under as...
متن کاملPositioning Control of Pneumatic Servo System with Pressure Control Loop Using Disturbance Observer
This paper describes one method to attain a robust positioning control of pneumatic driving system comprising a pneumatic cylinder and PCM digital control valves. A pneumatic driving system has become one of interests in the industrial fields, however, the control characteristics are inevitably affected by the friction force and parameter changes of plant due to air compressibility. The control...
متن کاملAdaptive Fuzzy PID Control for Servo Motor Direct-drive Pump Control System
The direct-drive pump control system has been gradually applied to the industrial control field due to its high control precision, fast response, small throttle loss and compact structure. This paper adopts the fuzzy PID control method to resolve the hydraulic cylinder position servo control of direct-drive pump control system. The system model and fuzzy PID control algorithm was established by...
متن کاملTrack-following control using a disturbance observer with asymptotic disturbance rejection in high-speed optical disk drives
To obtain a good tracking performance in an optical disk drive servo system, it is essential to attenuate periodic disturbances caused by eccentric rotation of the disk. As an effective control scheme for enhancing disturbance attenuation performance, disturbance observers (DOBs) have been successfully applied to the track-following servo system of optical disk drives. In disk drive systems, th...
