Abstract:
With the advancement of science and technology, there is an increasing need to control complex systems in changing environments where nonlinearity, time delay, uncertainty and coupling are the main sources of complexity. This talk will present two recent results to show how sliding mode techniques are applied to deal with complex systems, and how to deal with the nonlinear uncertainties existing in the delayed systems. Lyapunov-Razumikhin approach is employed to deal with time delay. A sliding mode observer with simultaneous parameter estimation is given by combining the adaptive control approach. Then decentralised control scheme is proposed to control a class of complex interconnected systems using sliding mode techniques. Simulation results on bioreactor and river pollution systems to show the advantages of the proposed approaches. Finally, future research in the areas will be discussed.
