Excavator rotation energy recovery control method and system, excavator and storage medium
The invention discloses an excavator rotation energy recovery control method. The method comprises: establishing an engine equivalent fuel consumption function of an excavator under the cyclic working condition; wherein a control variable of the engine equivalent fuel consumption function is a motor torque or a generator torque, and a state variable of the engine equivalent fuel consumption function is a super capacitor SOC value of a system energy storage element; dividing the cyclic working condition into a plurality of stage working conditions, and solving an engine equivalent fuel consumption function corresponding to each stage working condition by adopting an iterative dynamic programming algorithm to obtain a global rotation energy control strategy; and executing rotation energy recovery operation according to the global rotation energy control strategy. According to the method, efficient recovery of the rotation energy of the excavator can be achieved, and the fuel economy of the excavator in the operation circulation process is improved. The invention further discloses an excavator rotation energy recovery control system, an excavator and a storage medium which have the above beneficial effects.
