%X To improve the performance of a low-pressure pneumatic servo system,a pulse-width modulation(PWM) linearization control method is proposed.The relay control method is replaced by PWM technology to control two switching valves of the system.By using Fourier transform,the output of the system is proved to be the superimposition of two outputs which are generated by the linear segment and the higher harmonic.The relation between the amplitude of the dither and load is computed and the steady-state output of th...
