Methods to analyze the characteristics of a valve-controlled pneumatic chamber under the PWM mode in both frequency and time domains are presented, and a PI control strategy for this system is proposed. A dual Fourier expansion method is used to obtain the transfer characteristics of the PWM and a first-order chamber model having flow direction dependent system parameters is employed to study the chamber frequency response. The steady-state behavior of the governing differential equations is obtained through time domain solutions. Predicted results of the frequency response are found to agree extremely well with the measurements obtained. Simulation results also reveal that the carrier frequency significantly affects the steady-state pressure response. Moreover, the feasibility of using a PI controller is demonstrated successfully through an experiment. The effect of the proportional and integral gains are also discussed.
