Abstract

The invention provides a device and method for improving the robust tracking control precision of a permanent magnet linear synchronous motor, and relates to the technical field of permanent magnet linear synchronous motor control. The device includes a power supply module, a detection circuit module, a DSP processor module, an IPM intelligent power module, a permanent magnet synchronous motor and a host computer module. The invention compensates the parameter uncertainty of the system through model feed-forward control, and improves the response speed of the system. The adaptive jerk controller is used to suppress uncertain factors such as external disturbance and friction in the system, and the adaptive law makes the robust gain converge within a bounded range, improving the robustness of the system; the output of the adaptive jerk controller After signal integration, a feedback control law is formed, which weakens the high-frequency resonance caused by the unmodeled dynamic excitation of the switching function in the control law, ensures the stability and continuity of the control signal, and improves the control accuracy of the permanent magnet linear synchronous motor servo system.

Description

technical field [0001] The invention relates to the technical field of permanent magnet linear synchronous motor control, in particular to a device and method for improving the robust tracking control precision of a permanent magnet linear synchronous motor. Background technique [0002] The traditional drive technology mainly adopts the rotary drive method of "rotary motor + ball screw". However, due to the transformation link in the middle, it will lead to bad consequences such as large motion inertia, reduced stiffness, slow speed, and poor stability. In order to avoid the inconvenience caused by the above-mentioned traditional driving methods, linear motors represented by permanent magnet linear synchronous motors adopt direct drive methods and are widely used in modern precision positioning systems such as semiconductor processing and electronic equipment manufacturing. Compared with the traditional drive method, the acceleration process of the direct drive method is s...
