摘　　要：汽油发电机转速变化的动态性能是影响发电机性能指标的一个重要因素。在分析小型汽油发电机数学模型和控制任务的基础上,提出了基于负载扰动前馈补偿的滑模控制算法,设计了滑模控制器,并加入了负载扰动前馈控制策略。利用MATLAB工具箱进行仿真和配机实验,并与常规滑模控制相比较。实验结果表明:在常规滑膜控制上采用前馈补偿后,系统的稳定性和动态性能都有了很大提高,证实了该方法的有效性。The speed dyrmnfic performance of a gasoline generator is an important factor that affects its electrical performances. To tackle this problem, this paper analyses the mathematical model of gasoline generator and its control task, proposes a load disturbances feed-forward com- pensation control algorithm. The paper designs the conventional sliding mode controller with and additional load disturbances feed - forward control strategy. The simulation of the speed control is implemented by MATLAB. The experimental results show that the proposed controller has superior characteristics in the static and dynamic perfomlances of speed stabilization. It is efficient in speed regulation for gasoline generator.
