Nowadays, elector-pneumatic regulator is widely used to a variety of practical pressure control applications. Fuzzy rule based PWM algorithm is newly proposed to save energy of electro-pneumatic regulator in this paper. A novel fuzzy rule based pulse width modulation(FRPWM) valve pulsing algorithm allows the electro-pneumatic regulator to become energy saving system. A comparison between the system response of conventional PWM algorithm and that of the proposed algorithm shows that the control performance is almost the same, but energy saving is greatly improved by adopting this new PWM algorithm. The effectiveness of the proposed FRPWM algorithm is demonstrated through experiments with various reference trajectories.
