Description
Summary:In this article, a novel self-evolving interval type-2 fuzzy systems based incremental life-long learning controller (SEIT2FS-ILLC) is proposed for robotic manipulators with unmodeled dynamics and external disturbance. The proposed controller structure that combines PID controller and SEIT2FS in parallel, allows for the construction of rule bases from scratch without the need for offline pretraining, while retaining the life-long learning and self-evolving structure abilities of SEIT2FS. Meanwhile, the introduction of FLS as a compensation controller in the proposed controller to improve the transient performance of the SEIT2FS-ILLC. Unlike most previous results, the proposed method does not rely on the mathematical model of the robotic manipulators but only on the input-output data of its operation. Utilizing the Lyapunov stability theory, the stability of the proposed controller is demonstrated. Both numerical simulations and actual robotic manipulators experiment to validate that the proposed method is effective.
