| Aiming at the problem of slow dynamic response during constant force tracking when the manipulator is in contact with the environment. An impedance control method based on real-time optimization genetic algorithm is proposed. In the research process, according to the comprehensive performance index of the response speed and control precision of the mechanical arm constant force tracking, the processing methods of the operator, such as the crossover, variation and calculation fitness value of the genetic algorithm in offline optimization, are improved, and the real-time optimization of control parameters for the impedance control is realized. The simulation results show that compared with the traditional control method, the method can improve the dynamic response speed of the mechanical arm and the environment contact force under the premise of ensuring the control precision, reduce the overshoot of the control process, and obtain better adjustment quality. |
