混合动力车辆机组的准滑动模态速度控制策略

Engine Speed Control and Simulation Based on Sliding Mode Control

发动机-发电机组作为混合动力电传动装甲车辆的主动力源,其协调控制能力直接影响到电传动装甲车辆的油耗、机动性和战场生存能力。为进一步加快发动机-发电机组的协调能力,强化发动机的调速性能,设计了基于准滑动模态控制的发动机转速控制器。对比传统的PID控制方法,上述方法不仅能够减弱外界的干扰,准确快速的完成发动机调速,而且缩短了调速时间,增强了发动机调速过程的稳定性和鲁棒性,同时还可以有效的抑制抖振的产生。通过基于Matlab/Simulink搭建的发动机调速模型,验证了上述方法的可靠性。

As the main power source of hybrid electric drive armored vehicles,the engine-generator directly af-fects the fuel consumption,maneuverability and battlefield survivability of electric transmission armored vehicles.In order to further strengthen the speed regulation performance of the engine,an engine speed controller based on sliding mode variable structure control was designed.Compared with the traditional PID control method,this method can not only reduce the external interference,accurately and quickly complete the engine speed regulation,but also shorten the speed regulation time and enhance the stability and robustness of the engine speed regulation process.At the same time,it can effectively suppress the generation of chattering.The reliability of the method is verified by the en-gine speed control model based on Matlab/Simulink.
