Generalized minimum variance self-tuning controller for MIMO systems

Based on a new generalized minimum variance performance index, a kind of generalized minimum variance self-tuning controller of multi-input multi-output systems (GMVSTC-MIMO) is proposed in this paper to give engineers another alternative of controlling multivariable stochastic processes. The design method of the controller is derived and the connections between the controller and the inverse Nyquist array (INA) method are also discussed.
