Abstract: A method for modulating pulse width for the pressure control of an electro-pneumatic regulator is provided to reduce the operation number and time of intake and exhaust valves by driving the inhalation and exhaust valves based on a saturation function value. A real pressure value is calculated in a pressure sensor(50). A value to subtract the real pressure value from a target pressure value is inputted to a PID(Proportional Integral Derivative) controller(10) as an input value and then the input value is outputted as an output value through the PID controller. The output value is calculated as a value between -1 and 1 through a saturation function(20). The calculated value is converted into a PWM(Pulse Width Modulation) output time so that intake and exhaust valves are driven when the sign of the saturation function is + and -. According to the driving of inhalation and exhaust valves, pressure of an electro-pneumatic regulator(40) is controlled and then an output value of the pressure sensor is generated.

Abstract: A pressure regulator using a piezoelectric actuator is provided to extend the lifespan of the pressure regulator by freely controlling the fluid pressure. Two pilot valves(40,50) are fixed at an upper portion of a regulator body(20) to control input and output of fluid. The fluid is inputted to an input port(21) formed at a lower portion of the regulator body and outputted to an output port(24) via a valve chamber(23) according to the open of a pressure valve(22). The pressure valve is operated under the control of a diaphragm(30). An input fluid path which is used for inputting the fluid to the pilot valve, is connected to the input port so as to drive the diaphragm. A diaphragm supplying fluid path which supplies the fluid from the pilot valve to a diaphragm chamber, is formed oppositely to a diaphragm exhausting fluid path at an upper portion of the diaphragm chamber. An exhausting unit(29) exhausts the fluid generated from the pilot valve.
