TLDR
A discrete-time proportional integral derivative controller, the manipulated variable of which takes two values, i.e., ON and OFF, is proposed and analyzed and a cascade type and a built-in type are proposed.Abstract:
A discrete-time proportional integral derivative (PID) controller, the manipulated variable of which takes two values, i.e., ON and OFF, is proposed and analyzed. Oversampling technology is employed in the controller design. As to the structure of the controller, a cascade type and a built-in type are proposed. An experimental example is presented.read more
