【摘要】：基于车载平台液压调平系统,为了减少支腿的跟踪误差及其同步误差,降低支腿之间的运动耦合,采用模糊PID控制算法实现调平过程中动态特性控制。利用AMESim和MATLAB/Simulink分别建立调平液压回路和模糊PID控制器的仿真模型并进行联合仿真研究。结果表明,加入模糊PID算法比常规PID算法能够有效的减少支腿的跟踪误差和定位误差以及支腿之间同步误差,有效提高调平精度。
[Abstract]:Based on the hydraulic leveling system of vehicle platform, in order to reduce the tracking error of the leg and the synchronization error, reduce the coupling movement between the legs, the fuzzy PID control algorithm to achieve the control of dynamic characteristics of leveling process were established. Simulation model of hydraulic loop and the fuzzy PID controller and combined simulation research using AMESim and MATLAB/Simulink. The results show that the fuzzy PID algorithm is added compared to the conventional PID algorithm can effectively reduce the synchronization error between the tracking error and positioning error of legs and leg, effectively improve the leveling accuracy.
