电磁式主动悬架模型预测控制器设计

针对已开发的电磁作动器样机，通过对电机控制电路模型进行简化分析，得到电磁作动器往复运动时控制电流可实现范围.考虑作动器约束和悬架许用行程，基于模型预测控制方法设计1/4车辆电磁主动悬架控制器，并分别针对瞬时垂向冲击和随机不平路面工况进行仿真分析.结果表明，相对于线性最优控制主动悬架，模型预测控制可以使车辆获得更佳的行驶平顺性能.

Model Predictive Controller Design for Electromagnetic Active Suspension

For the developed electromagnetic actuator prototype, the range of control current during the stroke of actuator was derived through analysis of simplified circuit control model. Based on model predictive control methodology, an active suspension controller was designed, which could take into account the constraints of actuator and quarter vehicle. The simulation results indicate that, under the condition of vertical shock and random uneven road, the model predictive controller can obtain better ride comfort than linear optimal control.
