Optimization and Simulation of CVT Electrohydraulic Servo System

文中建立了CVT电液伺服系统的传递函数,采用二次型优化理论对系统进行了优化。应用MATLAB/Simulink对系统进行仿真,得出阶跃响应图,并对优化前后系统的动态性能进行了对比分析。仿真结果表明,优化后系统的响应时间大幅减小,系统的动态性能得到改善。

This article first establishes the CVT servo system’s transfer function, then uses the quadratic form optimization theory to carry on the optimization to the system. Application of MATLAB/Simulink simulation of the system, come to step response plans and systems Optimization before and after the dynamic performance of a comparative analysis. The simulation result indicated that, after the optimization thesystematic response time largely reduces, the system dynamic performance is improved.
