Experimental verification of multirate and Model Predictive Control for discrete-valued control systems

A plant with discrete-valued control is considered in this study. In discrete-valued control systems, the control input resolution, which is determined by the minimum value of the amplitude of the discrete-valued input and period, directly affects the control performance. If insufficiently short per...

In discrete-valued control systems, the control input resolution, which is determined by the minimum value of the amplitude of the discrete-valued input and period, directly affects the control performance. If insufficiently short periods are specified, the control performance decreases due to the poor resolution of the discrete-valued input.
