【摘要】：将模糊PID的控制方法应用于超高压试验台,实现了超高压的比例精确控制。针对普通比例溢流阀无法调节超高压的问题,设计了超高压实现方案。为验证方案的可行性,用AMESim搭建了仿真模型,并确立了液阻大小、超高压泵的排量与转速范围等关键参数。为克服传统PID控制算法的不足,通过AMESim-Simulink联合仿真,并利用MATLAB的Fuzzy工具箱进行模糊PID控制器的设计。最后,搭建了Real-Time x PC Target实验平台,并进行了实验验证。实验结果表明系统的控制精度与超调均得到了改善。
[Abstract]:The fuzzy PID control method is applied to the ultra-high pressure test-bed, and the precise control of the ratio of the ultra-high pressure is realized. Aiming at the problem that the ordinary proportional relief valve can not adjust the ultra-high pressure, the realization scheme of the ultra-high pressure is designed. In order to verify the feasibility of the scheme, the simulation model was built with AMESim, and the key parameters such as liquid resistance, displacement and rotational speed range of the ultra-high pressure pump were established. In order to overcome the deficiency of traditional PID control algorithm, the fuzzy PID controller is designed by AMESim-Simulink co-simulation and Fuzzy toolbox of MATLAB. Finally, the Real-Time x PC Target experimental platform is built, and the experimental verification is carried out. The experimental results show that the control accuracy and overshoot of the system are improved.
