摘 要:将线性压缩机的机械和电磁两部分分别构建了物理模型。在物理模型基础上以驱动电压为输入、活塞位移为输出构建了线性压缩机状态方程;采用变速趋近律滑模控制算法设计线性压缩机控制器,并在Simulink中搭建线性压缩机控制系统;通过数值仿真方法与传统指数趋近律控制器进行对比,结果表明:变速趋近律滑模控制器在到达稳态时间、抖振程度上均优于传统指数趋近律控制器,并且在控制精度上提升了约20%,同时α=1.346、k=13.499时变速趋近律滑模控制器取得最优控制效果,通过试验测试得到控制误差在4%~7.8%之间,验证了控制器的控制精度及有效性。According to the structural characteristics and working principle of linear compressor,the control strategy of linear compressor was divided into mechanical and electromagnetic parts.The physical models for the two parts are constructed respectively.On the basis of the physical model,the linear compressor state equation was constructed with the driving voltage as the input and the piston displacement as the output.The variable speed reaching law sliding mode control algorithm proposed in this paper was used to design the linear compressor controller,and the linear compressor control system was built in Simulink.The present method was compared with the traditional exponential reaching law controller by using the numerical simulation.The results show that the sliding mode controller with variable speed reaching law is superior to the controller with the uniform exponential reaching law in the steady-state time and chattering degree,and the control accuracy is improved by 20%.At the same time,whenα=1.346、k=13.499,the sliding mode controller with the variable speed reaching law achieves the optimal control effect.The control error is between 4%and 7.8%,which verifies the control accuracy and effectiveness of the controller.
