  tracking differentiator
     Differential signals of the driving chaos system and the controlled system were obtained by tracking differentiator and numerical differentiator. NPID controller was constructed with the principle that the integral of time-weighted absolute error(ITAE) was minimum,so that the available differential signals could be used to force the output of controlled system to follow the chaotic trajectory of the given driving system.

In order to realize chaos robust anti-control of a class of nonlinear system with uncertainties,a nonlinear proportional integral differential(NPID) control method was put forward.Differential signals of the driving chaos system and the controlled system were obtained by tracking differentiator and numerical differentiator.NPID controller was constructed with the principle that the integral of time-weighted absolute error(ITAE) was minimum,so that the available differential signals could be used to force the output of controlled system to follow the chaotic trajectory of the given driving system.Using this method,chaos anti-control was not only extended from discrete system to continuous system but also from linear stable continuous system with clear structure and parameters to nonlinear systems with uncertainties of structure and parameters.Analysis and simulation results show that differential signals of the driving chaos system and the controlled system can be obtained precisely,and the suggested controller design method is free of the constraints of Lyapunov exponents allocation which is often difficult to get.
