The conditions for the practical stability of the system output feedback exponent are given. The uncertainties of the controlled system can be nonlinear Or time-varying • Input channel uncertainties meet general limits • Systems boundary of uncertainties exists but is unknown • Design deterministic adaptive controllers ensure that the state of the controlled system is finite. The time converges to a specified neighborhood near the equilibrium point of the system at a specified exponential rate. The simulation results show that the conclusions obtained are correct and valid
