Abstract

The invention relates to an overshoot control method of a composite shaft control system realized based on a Matlab platform, and belongs to the technical field of composite shaft control. The composite axis control system of the present invention designs a pre-aiming process according to the target position when the input signal x is given, that is, a preview module is set between the input signal and the subsequent link of the composite axis control system, and the preview module The output y replaces the given input signal x as the input signal of the composite axis control system. When the target is within the tracking field of view, the fast mirror is used for high-precision tracking compensation. The speed makes the simulation model under the Matlab platform closer to the actual system , which solves the problem of serious overshooting phenomenon in the existing composite shaft control system.

Description

technical field [0001] The invention belongs to the technical field of composite shaft control, and in particular relates to an overshoot control method of a composite shaft control system realized based on a Matlab platform. Background technique [0002] Compound axis control is a new control method in recent years, which mainly compensates the residual deviation of the conventional control system by virtue of the characteristics of fast response and high precision of the fast mirror. In the composite axis control, the conventional control system is used as the main control system (main axis), and the control system including the fast mirror is used as the sub-control system (sub-axis). When the input signal is fixed, there is no pre-aiming process designed according to the target position, so the overshoot phenomenon is serious. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the invention is: how to...
