For the problem of vertical-moved and discontinuous stator resulting from disturbance, this paper proposes an dual mode composite control structure for permanent magnet linear motor to prevent stepping out. The composite controller is designed containing fuzzy control, neural network control and genetic algorithm. The mechanism of the control and parameter optimization method for fuzzy neural n...

Embedded systems tightly serve the needs of consumer electronics, home automation and portable devices. During the period of developing embedded systems, code generation is always seen a design challenge because every embedded processor has its own specific characteristic. In this paper, we propose a retargetable code generation (RCG) methodology which can generate retargetable C program for em...

Functional electrical stimulation (FES) sometimes applies to patients with partial paralysis, so human voluntary control and FES control both exist. Our study aims to build a cooperative controller to achieve human-FES cooperation. This cooperative controller is formed by a classical FES controller and an impedance controller. The FES controller consists of a back propagation (BP) neural networ...

The mosquito life cycle is developed mathematically with the concept of difference equation. qualitative properties life-cycle are analyzed. Lyapunov function defined for equation to stabilize system cycle. A novel technique applied deriving stability criterion, especially back-stepping control discrete time system. bifurcation analysis also furnished model new in and its results examined throu...

The original back-propagation methods were plagued with variable parameters which affected both the convergence properties of the training and the generalisation abilities of the resulting network. These parameters presented many difficulties when attempting to use these networks to solve particular mapping problems. A combination of established numerical minimisation methods (Polak-Ribiere Con...

In this paper an Artificial Neural Network (ANN) based controller is presented for the Automatic Generation Control (AGC) of a five area interconnected power system with reheat turbines. The control scheme guarantees that steady state error of the area frequencies and inadvertent interchange of tielines are maintained in a given tolerance limit. ANN controller controls the inputs of each area i...

In this paper, we design an image tracking system which is composed of two cameras and two stepping motors. First, The image pair of a moving target is grabbed by two cameras continuously. The horizontal and vertical distances between both centers of this moving target and the image can be determined by using image processing methods. Furthermore, a fuzzy logic controller pair is designed to co...

We present a framework for composing motor controllers into autonomous composite reactive behaviors for bipedal robots and autonomous, physically-simulated humanoids. A key contribution of our composition framework is an explicit model of the “preconditions” under which motor controllers are expected to function properly. Pre-conditions may be determined manually or learned automatically by alg...
