불확실한 시간 변화 매개변수를 갖는 비선형 시스템에 대한 강력한 적응 제어를 설계하는 문제가 해결되었습니다. 제어 계수에서도 고려되는 불확실한 매개변수의 상한을 알 필요는 없습니다. 적응형 추적 컨트롤러가 제시되고 Lyapunov 이론을 사용하여 폐쇄 루프 안정성과 추적 오류 수렴이 표시됩니다. 방법의 성능을 향상시키기 위해 견고한 메커니즘이 적응형 컨트롤러에 통합되어 견고한 적응형 알고리즘을 생성합니다. 제안된 컨트롤러는 경계를 알 수 없는 시변 매개변수 불확실성에도 불구하고 모든 폐쇄 루프 신호의 경계성과 추적 오류의 강력한 수렴을 보장합니다. 고려 중인 모수적 불확정 시스템은 광범위한 종류의 비선형 회로 및 시스템을 설명합니다. 응용으로서, 비선형 Chua 회로에 대한 새로운 매개변수 모델을 도출하고, 제안된 방법을 제어에 사용한다. 이 방법의 효율성은 일부 시뮬레이션 결과를 통해 입증됩니다.

Abstract: The problem of designing a robust adaptive control for nonlinear systems with uncertain time-varying parameters is addressed. The upper bound of uncertain parameters, considered even in control coefficients, are not required to be known. An adaptive tracking controller is presented and, using the Lyapunov theory, the closed-loop stability and tracking error convergence is shown. In order to improve the performance of the method, a robust mechanism is incorporated into the adaptive controller yielding a robust adaptive algorithm. The proposed controller guarantees the boundedness of all closed-loop signals and robust convergence of tracking error in spite of time-varying parameter uncertainties with unknown bounds. The parametric uncertain systems under consideration describes a wide class of nonlinear circuits and systems. As an application, a novel parametric model is derived for nonlinear Chua's circuit and then, the proposed method is used for its control. The effectiveness of the method is demonstrated by some simulation results.
