Abstract :
An efficient design method to improve the control performance of rough controller which integrates the Bang-Bang control rules with PID control rules is presented in this paper. The two parts of rules extracted from Bang-Bang controller and PID controller by rough set, respectively, are combined to a uniform decision making system under a certain selection mechanism. This rough controller reserved all the advances of Bang-Bang control and PID control enables to deal with different magnitudes of set point variation and large disturbance. Simulations show the effectiveness of this method.
