This paper presents a state feedback controller (SFC) for position control of PMSM servo-drive. Firstly, a short review of the commonly used swarm-based optimization algorithms for tuning of SFC is presented. Then designing process of current control loop as well as of SFC with feedforward path is depicted. Next, coefficients of controller are tuned by using an artificial bee colony (ABC) optimization...
The paper discusses selected modifications to a constricted, i.e. canonical, version of the particle swarm optimizer (PSO) enabling effective operation of a repetitive controller. The recently developed plug-in direct multi-swarm repetitive controller (PDMSRC) for the sine wave constant-amplitude constant-frequency (CACF) voltage-source inverter (VSI) with an output LC filter serves as a case study...
This paper presents evolutionary optimization of the linear quadratic regulator (LQR) for a voltage-source inverter with an $LC$ output filter. The procedure involves particle-swarm-based search for the best weighting factors in the quadratic cost function. It is common practice that the weights in the cost function are set using the guess-and-check method. However, it becomes quite challenging,...
