Nonlinear adaptive control method based on ANFIS and multiple models

Abstract This paper presents the general concept of the nonlinear control of the asynchronous machine. The decoupling between the flux and the speed is realized by the input-output linearization technique. In this work, a nonlinear adaptive control method has been applied to the asynchronous machine and we give some initial results on the adaptive fuzzy logic control of nonlinear systems, linearized by state feedback. The adaptations of the parameters are used as a technique for robustifying the exact cancellation of the nonlinear terms, which is called for the linearization technique. The performance of the proposed nonlinear adaptive control scheme is demonstrated by simulation results. These results show that the proposed method achieves the desired dynamic performance.

Magneto Rheological

This study examined automobile vibrations by using a half vehicle model, and its vertical and angular vibrations were suppressed by means of the nonlinear adaptive control of a magneto-rheological damper. The control method was designed in such a way that it did not need to measure the road input to suppress the vibrations by the use of adaptive road observers. Therefore, disadvantages such as measurement difficulty and cost were also eliminated. Instead of completely experimental test rigs, the hardware-in-the-loop simulation which is a hybrid method was preferred due to it being easier to set up, cheaper, and also it had a close response to the full experimental system. The experimental responses obtained by the proposed adaptive control method with adaptive road observers and the nonlinear adaptive control method in which the road disturbances were measured were compared in the time and frequency domains. Finally, the effectiveness of the proposed method was shown using some figures, root mean square values, and performance indices.

Nonlinear Adaptive Control

In this paper, the characteristics of underactuation are analyzed according to the working principle of underwater glider, a complete 6DOF model of underwater glider is established, and the error equation of 3D path tracking is given. Based on the line-of-sight navigation method in three-dimensional space, the nonlinear adaptive control strategy is designed, and the roll angle control law, pitch angle control law, and depth control law of underwater glider are given. The tracking error of underwater glider is proved to be convergent by Lyapunov stability theorem. Finally, the results of marine experiments verify that the nonlinear controller designed in this paper can overcome the influence of constant current disturbance under certain conditions and has good robustness and good tracking effect under different ocean current sizes and course angles. Of course, one control method cannot be applicable to all sea conditions. When the angle between the size and direction of the ocean current exceeds a certain value, the tracking control of the underwater glider will show obvious divergence. Therefore, the stability range against the interference of the sea current is given in this paper.
