Comparison research on pid controller and model-free controller based on multi-innovation theory

摘要

We introduce the basic theory and design method of model-free learning adaptive controller (MFLAC) in this paper. Then a improve method of MFLAC based on multi-innovation theory is presented. Simulation results show that MFLAC and proposed MFLAC have better performance to PID controller for unstable system; what's more, the proposed model-free controller has faster convergence rate and better tracking performance.
