Hybrid Adaptive Bionic Fuzzy Control Method

Abstract EN

The bionic fuzzy system embeds the biologically active adaptive strategy into the traditional T-S fuzzy system, which increases the active adaptability.

On the basis of the researches, an identification model is added to the system, and a hybrid bionic adaptive fuzzy control method is proposed in this paper, which makes the system have biological adaptability and strong anti-interference ability.

The adaptive law contains two items: the first one is the general term for adjusting system parameters by using the current state and the second one is a compensation item for the adjustment of system parameters based on the development trend.

Lyapunov synthesis method is used to analyze the stability and convergence of system.

The design method of fuzzy controller, adaptive laws, and parameter constraints are given.

Finally, the effectiveness of the method is verified by simulation of inverted pendulum model.
