| description | The invention discloses a differential evolution algorithm-based electro-hydraulic servo system PID (Proportion Integration Differentiation) parameter optimization method, which comprises the following steps of forming a three-dimensional row vector by taking three parameters of a proportionality coefficient KP, an integral coefficient KI and a differential coefficient KD to be optimized as components, carrying out floating-point number coding to form an individual of a differential evolution algorithm, and carrying out differential evolution on the individual of the differential evolution algorithm; taking a reciprocal of a system performance index as a fitness function of a differential evolution algorithm, and adopting a maximum number of iterations as a termination condition; and after the operation reaches the specified iteration times, stopping operation, and taking the optimal individual in the current group as the optimal solution of a PID parameter.
