Abstract

The invention discloses an output restraint bearing fixed time tracking control method for a mechanical arm system. The method includes describing a dynamic equation of a mechanical arm system of a rigid body structure; a continuous fixed time trajectory tracking control rule is set by utilizing a barrier Lyapunov function method and a finite time control algorithm when external interference is not taken into account; designing a fixed time trajectory tracking controller according to the obtained control rule so as to enable a state trajectory of the dynamic equation of the mechanical arm system to track a preset expected trajectory in a fixed time and to prevent tracking errors during a control process from surpassing a preset boundary; and performing tracking control by utilizing the fixed time trajectory tracking controller. The method provided by the invention has good convergence and good interference immunity.

Description

Technical field [0001] The invention relates to a fixed time tracking control method of a mechanical arm system with output constraints. Background technique [0002] Although the robotic arm system is not as flexible as the human hand, it has the characteristics of being able to repeatedly work and labor, not being tired, not afraid of danger, and having greater power to lift heavy objects than a human hand. Therefore, the robotic arm has been valued by many departments. It is more and more widely used. For example, the loading and unloading of workpieces processed by machine tools, especially in automatic lathes and modular machine tools, is more common; it is widely used in assembly operations. It can be used to assemble printed circuit boards in the electronics industry, and it can be used in the machinery industry. To assemble parts; it can work in poor working conditions, monotonous and repetitive and easy to fatigue working environment to replace human labor; it can work ...
