Abstract

The invention belongs to the field of control systems, particularly relates to a light flexible system distribution control method and system based on IPMC driving and devices, and aims to solve the problems of controller overflow, low control precision and slow response easily caused by a traditional control method. The method comprises the steps that a control task and the real-time displacementof the free end of the light flexible system are acquired, the real-time displacement is converted into a voltage signal, a driving electric signal is acquired through a light flexible system distribution parameter model based on the voltage signal and the control task, an IPMC is controlled to perform corresponding actions based on the driving electric signal, the control over the light flexiblesystem is completed, and vibration is restrained. By establishing the distribution parameter model of the light flexible system with high nonlinearity and coupling characteristics and designing the Lyapunov function, the vibration problem of the light flexible system is effectively suppressed, so that the light flexible system is more accurate in control, faster in response speed, higher in safety and higher in universality.

Description

technical field [0001] The invention belongs to the field of control systems, and in particular relates to an IPMC-driven distributed control method, system and device for a lightweight flexible system. Background technique [0002] In recent years, people's continuous exploration of the field of robotics has made it develop rapidly. Among them, flexible mechanisms such as flexible manipulators and flexible beams are more and more used in important fields such as aviation and medical treatment because of their advantages such as light material, soft structure, strong flexibility, and low energy consumption. However, the shortcomings of this type of lightweight flexible system are also obvious, such as the vibration problem of the flexible suspension beam, which brings great challenges to the precise control of the lightweight flexible system. Aiming at the vibration control problem of this kind of light flexible system (distributed parameter model), the present invention se...
