A Development of Embedded System for Speed Control of Hydraulic Motor

Abstract

In the present study, a high-performance electro-hydraulic motor controller is designed and
developed by using embedded technology. These electro-hydraulic motor is controlled using designed
algorithms in ARM7embedded board with graphical programming. An optical encoder is used to
detect hydraulic motor speed by reading via timer in ARM7. Hydraulic proportional valve is
employed to control the flow of hydraulic motor by manipulating PWM signal. The control
approaches have been tested for the function ability of the actuator, which is speed control. The
results have shown that the system works successfully and gives good performance for practical
applications.
