Research on self-turning minimum variance control algorithm in non-minimum phase system

Nowadays, with the development of modern automatic production, the applicability of automatic control algorithm has been expected for higher requirements, especially in the field of modern engineering. In this paper, we have studied the traditional self-turning control method by minimum variance, analyzing its shortcomings in system identification and model construction. At the same time, to make up for the limitation that it is not suitable for non-minimum phase system, a method to increase the state tracker by using system stabilization is proposed. This method solves the problem of how to design the self-turning minimum variance control in non-minimum phase system.
