| Abstract: | Structure and working principle of electric load simulator were introduced, friction on influence of electric load simulator was analyzed, and mathematical model of the load simulator was established. The adaptive fuzzy PID setting control method was proposed to design the controller for eliminating friction nonlinear factor on influence of electric load simulator,and feed - forward compensation based on structure deformation principle was proposed to restrain surplus torque. |
