An attitude controller is designed for a flexible structure using H ∞loop shaping approach together with two stage stabilizing procedure and simulation results are presented.
Singlechip AT89C2051 is selected to realize the speed closed loop control as the control core in order to most simplify the controller's design of brushless DC motor(BLDCM).
Second, a combined PID and fuzzy controller is designed for the bandwidth-limited active suspension system and then programmed by means of S-functions in Matlab/Simulink, to which a data exchange interface with ADAMS/View is also defined.
A PD-controller is designed that provides the required control of the relative motion of the middle legs.
Our proposed robust adaptive controller is designed to identify on-line the unknown control directions and is a switching type controller, in which the controller parameters are tuned in a switching manner via a switching logic.
In view of characteristics and requirements of the system, a hybrid intelligent PID controller is designed specifically based on dynamic simulation.
A force controller is designed to communicate the control signal between the simulator and digital controller.
