An algorithm of optimal settings for PIDD2D3-controllers in ship power plant

Abstract

The analysis of the operation of PID regulators is performed with both perfect differentiation and taking into account the real differentiation of the controlled variable s deviation. Compared the sensitivity of automatic control systems (ACP) with a PIDD2D3 controller tuned to a minimum of the integral criterion for the modulus and a minimum of the linear integral criterion with the same stability margin according to a given value of the oscillation frequency index. The possibility of a robust compromise adjustment that guarantees the preservation of a given margin of stability under the predicted nature of the change in the dynamics of an object is considered.
