摘要: Multirate multivariable predictive control system with the sampling mechanism that adjusts
the plant inputs only once but detects the plant outputs several times during a period is
examined. The IMC structure of the system is derived, and its robust stability and zero
steady state error characteristics are analyzed. A new control algorithm is developed by
adding the variation of the outputs to the index performance. The simulation results show
that the method is effective and has zeros steady-state error.
