%X Based upon the analysis on the square root B-spline approximation used in the probability density function (PDF) shape control,this paper proposes a new strategy which transfers such an optimal tracking control into an optimal control design issue under a nonlinear state constraint.A robust variable structure controller (VSC) and a nonlinear observer are then designed according to such a nonlinear state constraint and the characteristic of the system model.A restrictive observation error has been ensured by using an error compensation mechanism.Simulation examples have indicated the effectiveness of the proposed algorithms.
