Abstract：This paper discusses the problem of the globally strongly stablilizing adaptive controller design for a class of nonhomogeneous high order nonlinear systems with unknow parameters, by defining an unknown parameter which need dynamic updating and a series of nonhomogeneous auxiliary functions, also by using the method of adding an integrator of the nonhomogeneous auxiliary function merging with adaptive technique, the restriction on the nonlinearities of existing results is relaxed and the sufficient conditions for the existence of continuous adaptive controller which guarantees the systems are globally strongly stable is given. A recursive design procedure is provided to achieve continuous adaptive state feedback control law. Finally, a simulation example is provided to illustrate the correctness of the theoretical results.
