【摘要】 本文针对CVT速比控制的特殊要求,在对比PID控制和模糊控制的控制效果基础上,结合两者优点,设计了混合型速比跟踪控制器,并利用Matlab/Simuink工具进行了起步、加速和坡道行驶等典型工况的仿真研究。仿真结果表明该控制器具有较强的鲁棒性和解耦能力,以及良好的动态响应能力和较高的稳态控制精度,在外界阻力的激励下仍具有良好的动态稳定性。更多还原

【Abstract】 Aiming at the special requirements of CVT ratio control and based on the comparison of control effects of PID control and fuzzy control,this paper designed mixed-type ratio tracking controller combining the advantages of both PID and fuzzy control.Using Matlab/Simuink,simulation research of typical working conditions was made,such as start up,acceleration and ramp moving.The simulation results showed that the controller has strong capacity of robust and decoupling and good dynamic response and high accuracy Control of steady state,and good dynamic stability under the resistance of outside environment.更多还原
