In this paper, we propose a multivariable Model Driven (MD)-PID control system which is composed of MDPID control systems with PD feedback and inverted decoupling, discuss properties of the control system and also introduce a simple continuous system modeling by using CMA-ES and SIMULINK model, numerical example of a TITO process shows the practically effectiveness.

In this paper, a practical limit cycle predicting method is proposed for analyzing stability of nonlinear multivariable feedback control systems. The stable limit cycle of the considered system is found first by six criteria for unity loop gains, and then the stability is evaluated for variable loop gains. It needs only to check maximal or minimal frequency points of root-loci of equivalent gai...
