Fuzzy control

Magnetic ball bearing systems are applied in many different fields in industry and some aviation fields. In this system, the magnetic ball bearing serves as a conventional ball bearing, but the very obvious difference between these two types is that the object is held fixed or movable between two or more magnetic poles of the electromagnet.

This paper introduces a practical and simple power control method for wind energy conversion systems based on a doubly-fed induction generator. Due to the limitations of traditional proportional-integral controllers when the parameters of the doubly-fed induction generator and wind speed vary, fuzzy control theory is applied to overcome these challenges.

This paper presents a system that combines torque control algorithms based on a back-propagation neural network (BP-ANN) and an Adaptive Neuro-Fuzzy Inference System (ANFIS). The BP-ANN uses a multi-layer structure where the input layer processes factors such as load torque, rotational speed, and stator current, hidden layers model complex nonlinear interactions, and the output layer predicts optimal torque for AFPMSM operation.

The article focuses on developing an adaptive electronic stability controller for electric cars modelled on software MatlabSimulink. Design a vehicle stability controller within the scope of surveying the slippage of four tyres in the stability limit ellipse corresponding to the driving angle when using a fuzzy adaptive electronic stability controller (Fuzzy-ESC) compared to compared with the electronic stability control swarm optimization controller (PSO-ESP), it minimizes skids and vehicle rollovers during obstacle avoidance, lane changing, corner entry/exit and sudden acceleration.

This chapter describes the joint application of two soft computing methods – evolutionary algorithms and fuzzy reasoning – to the problem of adaptive distributed routing control in packet-switched communication networks. In this problem, a collection of geographically distributed routing nodes are required to adaptively route data packets so as to minimise mean network packet delay. Nodes reach routing decisions locally using state measurements which are delayed and necessarily only available at discrete sampling intervals. ...
