【摘要】 汽车巡航控制手统属于车辆的纵向控制,具有很强的时变性和非线性,对控制算法的兽棒性要求较高,传统基于PID控制算法难以达到满意的控制效果。本支采用兽棒性较强的自抗抗控制技术,并针对ADRC谚计过程中需整定的参数多,整定、忧化困难的特点,通过遗传算法与车辆纵向动奇学模型进行了联合仿真,实现了控制器参数的忧化整定。仿真结果表明,ADRC具有很强的鲁棒性,能够较好地解块巡航控制过程中非线性、时变以及存在内扰、外扰控制粗暴等问题。更多还原

【Abstract】 The longitudinal control of automotive cruise control system(CCS) has very strong time-varying and nonlinear characteristic,which acquires high robustness of the CCS’s control algorithm.So the traditional PID control algorithm can’t achieve sound effects.And aiming at the characteristics in vehicle longitudinal controlling,auto disturbance rejection control(ADRC),which has high robust,is introduced.At the same time,in allusion to the fact of many parameters and great difficulty to tune and optimize them,combining Genetic Algorithms(GA) and co-simulation with the established CCS longitudinal dynamics model together,the optimized ADRC parameters are attained.Consequently,the simulation result also shows the great robust of ADRC,which can solve the problems well during the process of cruise Control such as nonlinear,time-varying and the rough control of both internal and external disturbance,etc.更多还原
