System stability

This paper presents methods for controlling a real model using the S7-400 controller with SCL language (Structured Control Language). The two controllers designed are the hybrid Neural Network Neural-PID (Proportional Integral Derivative) controller and the RBF (Radial Basis Function)- PID controller.

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 paper concerns a problem of finite-time stability for a class of linear singular large-scale systems with delays. Based on matrix transformations, Lyapunov function method combined with new estimation techniques, we derive sufficient conditions for solving the finite-time stability of the system.

This paper deals with synchronization analysis problem for a class of fractional-order neural networks with unbounded delays. Using the Lyapunov function method combined with fractional Halanay inequality, we derive a novel sufficient condition for asymptotic stability of the error system resulting in two neural networks are synchronized.
