以多功能路面清雪车电液比例阀控系统为研究对象,提出了一种提高多功能路面清雪车运作率的模糊-智能PID(Proportion Integral Differential,比例、微分、积分)复合控制器,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。该控制器能够弥补常规PID控制因某些原因造的系统不稳定,将PID控制的简单、鲁棒性好和可靠性高等优点应用到模糊控制系统中,充分显现模糊控和PID控制的双重优点。简单概述了模糊控制的原理、特点和PID控制的原理等基本知识。鉴于智能PID制与模糊控制相结合的原理的可行性而提出了模糊-智能PID控制器,并将其应用在清雪车的液压系统中通过仿真试验证明它的可行性。
Taking the electro-hydraulic proportional valve control system of multi-functional pavement snow-cleaning vehicle as the research object, a compound controller of fuzzy-PID (Proportion Integral Differential, proportional, differential, integral) And compared with the conventional PID control fuzzy control strategy such as comparison and demonstration, simulation analysis and experimental study. The controller can make up for the conventional PID control system instability made for some reason, the advantages of simple PID control, good robustness and high reliability are applied to the fuzzy control system to fully demonstrate the dual advantages of fuzzy control and PID control . A brief overview of the fuzzy control theory, characteristics and PID control theory and other basic knowledge. In view of the feasibility of the principle of the combination of intelligent PID control and fuzzy control, a fuzzy-intelligent PID controller is proposed and applied to the hydraulic system of snow car to prove its feasibility through simulation.
