The algorithm of automatic parametric optimization (APO) of a PI controller with semi-permanent integration is considered. The algorithm is based on a gradient scheme. The components of the gradient of the optimization criterion are calculated on the basis of the methods of the theory of sensitivity. The advantage of such an algorithm is that all configurable parameters are simultaneously adjusted at each iteration of the algorithm. The optimized regulator belongs to the class of regulators with variable structure.
