摘要
针对电动助力车频繁启动和刹车造成的制动能量浪费等问题,在研究和建立了永磁无刷直流电机驱动、制动电路结构和数学模型的基础上,设计了能量回收电动助力车控制器.针对速度-电流双闭环调速控制系统的内环电流环,应用鲁棒控制理论设计了H_∞鲁棒控制器,并与应用了PID控制器的闭环系统进行了比较.结果表明,H_∞鲁棒控制器在系统建模中的参数不确定性抑制、抗干扰、响应速度等方面均优于传统的PID控制器,而且应用H_∞控制器可使助力车续行里程比例提高到1.8%~2.6%.
Based on the analysis of driving and regenerating circuit for the brushless DC motor, the regenerating controlling system is designed to lower the energy dissipation due to frequent starting and braking. Focusing on the speed-current double closed loops system,H∞ controller is developed. The experimental results show that H∞ outperforms the traditional PID controller for resisting perturbation, accelerating, response, and the controller enables to extend the mileage by 1.8% to 2. 6%.
