Performance analysis of model-free PID tuning of MIMO systems based on simultaneous perturbation stochastic approximation
We present a performance comparison of SPSA based methods for PID tuning of MIMO systems. The performance is analyzed in terms of the stability of the closed-loop system, tracking performance and computation time. The GSPSA algorithm is the most practical in terms of the stability and the tracking performance.
