... solution of a low-order problem. Tornero, Gu, and Tomizuka [3] studied the multi-rate controller, which updates the controller output faster than the measurement sampling frequency by a factor of N. The controlled system is continuous, and the discrete time controller is obtained as its zero order hold equivalent. The simplest case ...
