摘要：

为了降低液压机械无级变速器使用的容积调速系统进行转速控制的波动性，设计了遗传算法(GA)优化PID的控制方法，并通过AMESim与MATLAB/Simulink联合软件开展了仿真分析。研究结果表明：通过GA优化PID控制方法进行优化后，转速达到了0.35%的超调量，经过0.25 s达到稳定状态，与传统PID控制方式相比，超调量降低了18.5%，所需调节时间缩短了0.17 s，显著降低了转速的波动性。采用GA优化PID控制方式进行优化，可以使系统获得更短的调整时间，达到更高效的响应性能，大幅减小了转速的超调量，显著提升了系统调速性与稳定性。使系统获得了更优的动态响应性能与转速控制精度，为最终满足工程应用提供了有利条件。

In order to reduce the fluctuation of rotation speed control for volumetric speed regulation system used in hydro-mechanical continuously variable transmission(HMCVT), a control method of PID optimized by genetic algorithm (GA) was designed, and the simulation analysis was carried out by AMESim and MATLAB/Simulink combined software. The results show that after optimization by the control method of PID optimized by GA , the rotation speed reaches overshoot of 0.35% and shows stable state after 0.25 s. Compared with the traditional PID control method, the overshoot is reduced by 18.5%, the required adjustment time is shortened by 0.17 s, and the fluctuation of rotation speed is significantly reduced. Thus, the control method of PID optimized by GA can make the system obtain a shorter adjustment time, achieve more efficient response performance, greatly reduce the overshoot of rotation speed, significantly improve the speed regulation and stability of the system, and obtain better dynamic response performance and rotation speed control precision, which can provide favorable conditions to meet the engineering application.
