Abstract

The invention discloses a micro electromechanical system gyroscope fuzzy self-adaptive control system based on fuzzy compensation. The micro electromechanical system gyroscope fuzzy self-adaptive control system comprises a micro electromechanical system gyroscope system and a control system. The control system comprises a reference model, a sliding framework self-adaptive controller and a fuzzy controller. The fuzzy controller comprises a controller main body, a fuzzy rule module, a parameter self-adaptive rule module and a robust fuzzy self-adaptive control rule module. The micro electromechanical system gyroscope fuzzy self-adaptive control system adopts an advanced control method to control the micro electromechanical system gyroscope, reduces effects of external disturbance on track tracing, especially effects of uncertain disturbance, reduces measurement errors, and guarantees that the micro electromechanical system gyroscope can work stably and efficiently.

Description

technical field [0001] The invention belongs to the field of intelligent control, and in particular relates to a fuzzy self-adaptive control system of a micro-electromechanical gyroscope based on fuzzy compensation. Background technique [0002] Fuzzy control is an important branch of intelligent control. Fuzzy electronic technology is the core technology of the 21st century and has been widely used in the electromechanical industry. The development direction of fuzzy control mainly includes Fuzzy-PID compound control, adaptive fuzzy control, expert fuzzy control, neural fuzzy control and multivariable fuzzy control. In essence, fuzzy control should be a branch of nonlinear control, and there are mainly two different forms: one is direct adaptive fuzzy control, that is, the fuzzy controller is directly designed according to the deviation between the actual system performance and the ideal performance; The other is indirect adaptive fuzzy control, that is, the model of the c...
