Research on the Pulse Width Modulated Pneumatic Servo Systems with Long Transmission Lines
This paper presents a nonlinear model of the pulse width modulated(PWM) pneumatic servo systems with long transmission lines which has a huge potential to be used in the automatic production lines and other industrial applications, for the advantages of low cost and clean. An averaging approach is adopted to describe the equivalent continuous-time dynamics of a PWM controlled nonlinear system. With this model, the simulation is taken with a fuzzy logic controller. The simulation results indicate that the PWM pneumatic servo system with long lines have good performance both in the position control and tracking ability.
