Potential Energy Recovery Control Strategy of Scissors Aerial Work Platform Using Improved NSGA-II

In this paper, the scissors aerial work platforms is taken as the object, and the kinematics model of the potential energy recovery system of the work platform is established to solve the problem of the energy loss of the downward potential energy of the electric push rod scissors aerial work platforms, and the downward recovery strategy of the work platform based on the motor brake is designed; Based on the existing NSGA-II optimization algorithm, the Gompers model was used to set the crossover and variation functions, and the dynamic crowding degree was used to select individuals to accelerate the algorithm’s convergence and improve the algorithm’s sensitivity. Matlab/SIMULINK software was used to simulate and analyze the descending process of the scissors aerial work platform to verify the correctness of the proposed recovery strategy. The research results show that the proposed potential energy recovery strategy based on the improved NSGA-II (I-NSGA-II) can ensure a safe descent speed of less than 0.17 m/s, and the possible energy recovery efficiency reaches 10.11% when the load is 280 kg.
