Abstract

Mostly Pulse width modulation (PWM) is the method that commonly used by the researchers on pneumatic project for the improvement in industry. This method will be applied into this project about how to control the speed of pneumatic cylinder with using On-Off solenoid valve. Currently, this method is not applying in the industry yet, however, the component that mostly used in industry is servo valve type. Unfortunately, by using the servo valve is very costly but it has its own advantage such a very long life time. Solenoid valve is implemented for reducing the cost of industry maintenance. Solenoid valve will conduct together with PWM so that, the speed can be control as well as if using servo valve. Besides that, the other components that will use the system are microprocessor bootloader PIC18F4550. The programming of PWM will be program into this microcontroller and the result will obtain by the waveform at oscilloscope and also the timing of movement retracted and extended from pneumatic cylinder.
