摘要
汽车制动器试验制动管压伺服系统是一个电-气-液非线性时变系统,是汽车制动器台架试验的重要内容。在分析制动管压伺服系统工作原理的基础上,建立制动管压电-气-液伺服系统数学模型。为了实现制动管压的快速和高精度伺服控制,结合PID控制和模糊控制的优点,提出一种模糊PID复合控制器的设计方法,并进行计算机仿真。M atlab仿真结果表明,该控制器具有响应快、超调小、适应性好、鲁棒性强等优点,较好地满足了控制要求。
The brake-pipe-pressure in automobile brake test is a typical electro-pneumatic-hydraulic,nonlinear and time-varying system,which is the important content in automobile-brake-platform-test. Gives the mathematic model of electro-pneumatic-hydraulic servo system of brake-pipe-pressure based on the analysis of the brake-pipe-pressure servo system. Considering the advantages of PID and fuzzy controls, a fuzzy-PID compound controller was introduced in order to achieve fast and high accurate control of brake-pipe-pressure. The results of computer simulation indicated this controller had the advantages of fast response, short overshoot, good adaptability and strong robustness, and it preferably satisfied control request.
