| Abstract: | This paper discusses the design of the hardware and software for PWM electrohydraulic proportional amplifier made up of single chip processor. The amplifier has such characteristics as searching for optimal frequency of PWM, compensating and correcting inherent hysteresis loop of proportional electromagnet, to output many kinds of time-current waveform, taking P1D closed loop control for the current flowing over the electromagnet etc. Furthermore, it has also such advantages as simple structure, convenient adjustment and test, low power consumption and low cost. |
