SYNCHRONIZATION OF A FOUR-WING HYPERCHAOTIC SYSTEM Masoud Taleb Ziabari 1and Ali Reza Sahab 2 1Faculty of Engineering, Computer Engineering Group, Ahrar University, Rasht, Iran 2Faculty of Engineering, Electrical Engineering Group, Islamic Azad University, Lahijan Branch, Iran ABSTRACT This paper presents synchronization of a four-dimensional autonomous hyperchaotic system based on the generalized augmented Lü system. Based on the Lyapunov stability theory an active control law is derived such that the two four-dimensional autonomous hyper-chaotic systems are to be synchronized. Numerical simulations are presented to demonstrate the effectiveness of the synchronization schemes.

PERFORMANCE COMPARISON OF TWO CONTROLLERS ON A NONLINEAR SYSTEM Kenneth O.M. Mapoka, Dr Tranos Zuva2, Howard Masebu3 and Keneilwe Zuva4 1Department of Agricultural Engineering and Land Planning, Botswana College of Agriculture, Gaborone, Botswana ABSTRACT Various systems and instrumentation use auto-tuning techniques in their operations. For example, audio processors, designed to control pitch in vocal and instrumental operations. The main aim of autotuning is to conceal off-key errors and allowing artists to perform genuinely despite slight deviation off-key. In this paper two, Auto tuning control strategies are proposed. These are Proportional, Integral and Derivative (PID) control and Model Predictive Control (MPC). The PID and MPC controller’s algorithms amalgamate the auto-tuning method. These control strategies ascertain stability, effective and efficient performance on a nonlinear system. The paper test and compare the efficacy of each control strategy. This paper gen...
