In this study, the dual-rate sampled-data control system is designed, where the sampling interval of a plant output is an integer multiple of the holding interval of a control input. Because the discrete-time Linear Quadratic Integrator (LQI) is used for optimizing the discrete-time control performance, intersample output might oscillate. To eliminate the oscillation of the intersample ripple caused by the input oscillation, the designed LQI controller is extended. Finally, the original LQI control law and the extended control laws are quantitatively compared.
