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

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.
