Abstract

The paper investigates switching tracking control and synchronization of four-scroll hyperchaotic systems via the Open Plus Closed Loop (OPCL) technique. Based on Routh Hurwitz criterion, con- trollers which enable the state variables of the system to either stabilize to a chosen position or track desired smooth time dependent functions at different time intervals are designed. Similarly, controllers which enable trajectories of the drive system to either synchronize or anti-synchronize with the trajectories of the response system at different time intervals are designed. Numerical simulations are presents to validate the effectiveness of the proposed tracking control and synchronization technique. The newly proposed switching tracking control and synchronization scheme could be used to improve the design and control of a switch regulator.
