Self-Tuning Control of Linear Systems Followed by Deadzones

The aim of the present paper is to increase the efficiency of self-tuning generalized minimum variance (GMV) control of linear time-invariant (LTI) systems followed by deadzone nonlinearities. An approach, based on reordering of observations to be processed for the reconstruction of an unknown internal signal that acts between LTI system and a static nonlinear block of the closed-loop Wiener system, has been developed. The results of GMV self-tuning control of the second order LTI system with an ordinary deadzone are given.
