Abstract

The invention discloses a nonlinear adaptive alternating current servo motor angular position control method and system. The method comprises the following steps: acquiring original motor rotor angular position data; inputting the original motor rotor angular position data to a motor rotor angular position control module; performing second-order time differential on the motor rotor position data to generate motor rotor angular acceleration data; inputting the motor rotor angular acceleration data and the output of a motor rotor angular position control module into an incremental inverse dynamics control module at the same time; and inputting the output of the incremental inverse dynamics control module to the motor current control module. According to the method, a motor model and a motor load model required by controller parameter setting are not needed, and the technical problems of difficulty in motor model and load model identification and controller time-varying parameter setting in the existing servo motor control technology are solved. Under the condition that the problems cannot be effectively solved in the prior art, the nonlinear adaptive control method which is simple, effective and high in performance is provided.

Description

technical field [0001] The invention relates to the field of motor control, in particular to a nonlinear self-adaptive AC servo motor angular position control method and system. Background technique [0002] With the continuous development of intelligent technology, more and more intelligent devices are used in people's life, work and study. The use of intelligent technology has improved the quality of people's life and increased the efficiency of people's study and work. In the field of motor control, the motor system is essentially a nonlinear, time-varying and uncertain system, and the design of the control system requires the use of nonlinear and adaptive control algorithms. [0003] At present, the servo control system algorithms of all motors adopt the traditional PID control algorithm. The PID control algorithm is a control algorithm based on a linear system. When using the PID algorithm to control a nonlinear servo motor, the problem encountered is how to set the pr...
