摘　　要：以多功能路面清雪车电液比例阀控缸位置控制系统为研究对象,针对被控对象非线性和时变性的特点,应用模糊理论提出模糊PID控制策略,设计了模糊智能PID控制器,并将其与常规PID控制、模糊控制等控制策略进行比较论证、仿真分析和试验研究。计算机仿真和实验研究结果表明:与常规PID控制、模糊控制等控制策略相比,模糊智能PID控制具有实时性好、响应速度快、超调小的特点,较好地满足了系统控制要求。Research on how to control the snow-clean vehicle＇s eldctro-hydraulic system, becauing of the character of nonlinear and intermittence we applying fuzzy thery , so bring forward fuzzy- intelligent PID control, also design the fuzzy-intelligent PID implement, compared with general PID controller or fuzzy controller we make a argumentation and emulational investigate. The re- sults of experiments show that fuzzy-intelligent PID hybrid control presented in the thesis is feasible and with good dynamic and static characteristic. This control policy has good real-time performance, quick response, little overshoot, electro-hydraulic proportional position control system with higher performance is obtained.
