Abstract
The disclosure discloses a nonlinear predicative position control method suitable for a biaxial permanent magnet servo system. In consideration of uncertainty disturbance of the biaxial permanent magnet synchronous motor driving system, a value function for the biaxial permanent magnet synchronous motor driving system and a constraint condition of the value function are constructed, and the value function is solved to obtain a voltage control quantity of the permanent magnet synchronous motor, and the voltage control quantity of the permanent magnet synchronous motor is input into the stator voltage input end of the permanent magnet synchronous motor, thereby realizing the adjustment control of the nonlinear prediction position of the biaxial permanent magnet synchronous motor driving system.
