【摘要】 结合发动机空燃比的控制特征,研究了一种能自适应补偿喷油量的CMAC控制器。介绍了其自适应补偿算法———学习—补偿法。通过采用台架试验数据加随机扰动数据并用MATLAB对CMAC进行训练和仿真,获取了控制器参数,验证了控制器的学习能力、鲁棒性和控制精度。更多还原

【Abstract】 Combined with control characteristics of engine air fuel ratio,the CMAC controller which is self adaptive to compensate fuel injection volume is studied.The self adaptive compensation algorithm,the learning—— — compensating method,is in tro duced.The CMAC is trained and simulated with data from rig tests along with random disturbance data to obtain the param eters of the con troller.The learning ability,robustness and control accuracy are validated.更多还原
