Application of the Single Chip Computer MCS-8098 in Electrohydraulic High Speed On-off Valve-controlled Systems

The microcontroller MCS-8098 was applied in the electrohydraulic high speed on-off valve controlled system. Its A/D functional circuitry, HSO unit and other units were used to realize the digital acquisition, the pulse width modulation (PWM) and pulse frequency modulation control strategies. The simplicity and high efficiency in the implementation of the digital PWM/PFM control for the electrohydraulic high-speed on-off valves controlled systems been experimentally testified.
