Abstract

The invention provides a high-precision control method of motor position servo system; the implementation of the system comprises the following steps: step 1, establishing a motor position servo system model; step 2, designing a high-precision motor controller based on limited time interference estimation; and step 3, adjusting parameters of the high-precision motor control law based on limited time interference estimation, so as to make the system satisfy the control performance index. The provided high-precision control method of motor position servo system establishes the motor position servo system model aiming at the features of the motor position servo system, and designs the high-precision motor controller based on the limited time interference estimation, so as to estimate and compensate unmodeled interference of the system at real time; the total disturbance of the system can be well estimated by adjusting the parameters of the control law, thereby being effectively solving the uncertain nonlinear problem of the motor servo system; the integral robust item ensures the overall stability of the system.

Description

technical field [0001] The invention relates to the technical field of a motor position servo control system, in particular to a high-precision control method for a motor position servo system. Background technique [0002] Because of its wide application in industry, high-performance control of motor-driven motion systems has attracted extensive attention including engineers and scientists. However, it is not easy to design a high-performance controller for a servo system. Due to changes in working conditions, external disturbances, and modeling errors, it is difficult to obtain an accurate model of the actual industrial process, and various faults in the system will also lead to model failures. Uncertainty, that is to say, the uncertainty of the model widely exists in the control system, so the designer is likely to encounter a lot of model uncertainty, especially unmodeled nonlinearity such as non-structural uncertainty. These uncertainties may seriously deteriorate the ...
