Abstract:To improve the performance of mining vehicle's hydraulic control system under the deep sea complex environment, the multiintegrator control algorithm based on mining vehicle's feature data was proposed to lessen random disturbance and increase the dynamic characteristic. In this algorithm, the feature data were identified firstly, then the expected output data of control system were calculated. With the feature data and the expected outputting data, the identification to the improved PID controller was completed. Simulation results show that it has effectiveness and feasibility.
