【摘要】 建立了高压气动容积减压系统的数学模型,给出了基于MATLAB -Simulink的高压气动容积减压PID -PWM控制系统仿真模型。仿真和实验研究结果证明高压气动容积减压控制系统的理论模型是符合实际的,并对PID -PWM控制方法用于高压气动容积减压系统的工作范围提出了指导性建议
【Abstract】 The mathematic model of the pressure reduction by expander in high pressure pneumatic system was created.The digital simulation model of the PID-PWM control system was obtained by Simulink in MATLAB,the experiment and simulation of the PID-PWM control system was performed.The results show that the mathematic model and simulation model are correct,and the PID control can be used in pneumatic pressure control system to some extent.
【Key words】 High pressure pneumatic system; Pressure reduction by expander; PID control; PWM control;
