HIGH-SPEED PLATFORM MOVEMENT PARAMETER SELF-TUNING METHOD BASED ON MODEL IDENTIFICATION AND EQUIVALENT SIMPLIFICATION

摘要

A high-speed platform movement parameter self-tuning method based on model identification and equivalent simplification, comprising: establishing test on a movement state of a high-speed platform, identifying a model parameter, and optimizing a movement parameter of an equivalent simplified model; selecting any one movement function from a pre-set parametric curve, setting an initial parameter, and driving the high-speed platform to move under the action of a controller and a driver; collecting dynamic response information of the platform, and calculating dynamic characteristic information such as rigidity, frequency, and damping of the platform; and establishing a dynamic response equivalent simplified model by using the acquired dynamic characteristic information, and optimizing the movement parameter in a selected parametric movement function by restricting to meet the movement accuracy and aiming at a shorter execution time, so as to obtain an optimal parameter.
