Abstract

Traditional fractional-order controller (FOPID) parameter tuning methods are mainly based on amplitude margin and phase angle margin in the frequency domain, and there are problems such as low parameter tuning efficiency and low accuracy. This paper proposes a parameter optimization method based on the multi-objective particle swarm optimization algorithm MOPSO. By rotating the Hankel matrix to approximate the fractional-order operator, the system fractional-order differential equation satisfied by the fractional-order controller parameters is transformed into an algebraic differential equation Using MOPSO to optimize controller parameters. Experimental results show that the design method improves the dynamic performance of the system and makes the system have good robustness.
