The speed dynamic performance of a gasoline generator is an important factor that affects its electrical performance. To tackle this problem, the paper analyzes the mathematical model of gasoline generator and control task, and proposes a quasi sliding mode control algorithm, designs the conventional sliding mode controller, and the simulation of speed control is implemented by MATLAB. The experimental results show that in guarantee the stability and dynamic of system are unchanged, the control algorithm can largely reduce the system buffet. It is efficient in speed regulation for gasoline generator%汽油发电机的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,本文在分析小型汽油发电机数学模型和控制任务的基础上,提出准滑模控制算法,设计滑模控制器,并利用MATLAB工具进行仿真和配机实验,与常规滑模控制相比较.实验结果表明:采用准滑模控制器后,在保证系统的稳定性、动态性能都不变的情况下,大大减小了抖振.证实了该方法的有效性.
