Electric cylinder power matching control system for excavator based on programmable controller

The invention discloses an electric cylinder power matching control system for an excavator based on a programmable controller, which relates to the technical field of excavators in engineering vehicles and comprises the programmable controller, a power management system, a servo driver, a bucket rod electric cylinder, a bucket electric cylinder, a movable arm electric cylinder and an electric cabinet. The power supply management system comprises a circuit breaker, a power supply protector, an electromagnetic filter, a contactor, a rectification filter circuit, a protection circuit, an IGBT, a single-chip microcomputer, a communication circuit and a heat dissipation module. The method has the beneficial effects that the optimal power matching relation is obtained by performing multi-objective optimization on the speeds and the thrust of the three electric cylinders by utilizing a bionic algorithm, so that the energy-saving property and the economical efficiency of the excavator are greatly improved, and the method is high in intelligent degree, stable and durable in work, safe, controllable and higher in environmental adaptability.
