【摘要】 针对汽车电子真空助力器系统非线性、惯性大、数学模型难以建立等特点,设计Fuzzy-PID分段复合控制器对其进行控制,并开发系统硬件在环仿真试验台对所设计的控制器进行仿真测试,在此基础上对系统进行实车试验。试验结果表明,所设计控制器能够保证控制目标取得良好的动态响应特性,系统能够快速、精确的响应制动指令,满足纵向驾驶辅助系统的使用要求。更多还原

【Abstract】 According to the non-linear,large inertia and difficulty of establishing exact mathematical model,a controller for the vehicular Electronic Vacuum Booster(EVB) system is designed based on a Fuzzy-PID staged composite control strategy.A hardware-inthe-loop simulator is built to test the validity of the controller.And then the system performance is confirmed by a serious of filed tests.Tests show that satisfying dynamic response characteristics are obtained and the system can respond to the command fast and exactly.It can satisfy the braking requirement of longitudinal driver assistance systems well.更多还原
