CHEN Weiquan;Huali College,Guangdong University of Technology;
In order to improve the stability of the multi-axis steering control of a mechanical transmission,a multi-axis steering control method for a mechanical transmission based on a nonlinear multi-rigid-body dynamics analysis is proposed,a steering dynamics model of a mechanical transmission is constructed to output a steering torque. A controlled object model of a multi-axis steering control of a mechanical transmission is constructed by using a constraint parameter such as a shift resistance and a load moment and the like,and a maximum gain adjustment of a multi-axis steering torque is realized by adopting an adaptive iterative learning control method. By using the nonlinear multi-rigid-body dynamics analysis method,the optimal control parameter estimation is carried out,and the multi-axis steering control lawoptimization design of the mechanical transmission is realized by combining the fuzzy tracking identification method of the expected track. The simulation results showthat the output stability of the multi-axis steering control of the mechanical transmission is good,the tracking error of the track is low,and the control quality of the mechanical transmission is improved.
