An adaptive fault-tolerant control strategy is proposed for a class of switched nonlinear systems with unknown functions and unavailable states by using the improved average dwell time technique and backstepping method. We use radial basis function neural networks（RBFNNs） to approximate the unknown functions and a switched nonlinear state observer is designed to estimate the unavailable states. In order to solve the explosion of the complexity problem, dynamic surface control technique is used. The presented fault-tolerant controllers and update laws guarantee the boundedness of all signals in the closed-loop system under a class of switching signals with average dwell time. Furthermore, the system output can track a given reference signal and the estimation errors converge to some small compact sets. Finally, an example is employed to illustrate the effectiveness of the proposed method.

第三十九届中国控制会议

作者： Wenqian Zhang Wenhan Dong Zongcheng Liu Yang Zhou Haoming Feng College of Aeronautics Engineering Air Force Engineering University

An adaptive tracking control approach is presented for pure-feedback systems with semi-bounded non-affine functions and dead-zone. The strictive bounded conditions are relaxed by the semi-bounded for continuous non-affine function, and then an adaptive filter is investigated by employing the dynamic surface control technique and invariant set theory. Furthermore, the actual control scheme with dead-zone is considered based on backstepping structure to eventually guarantee the controllability, and then the robust compensator is designed to reduce the influence caused by uncertainties and disturbances. Moreover, the result shows that all the closed-loop signals are bounded and the tracking error can asymptotically converge to a residual set. Finally, a numerical simulation example is stated to demonstrate the feasibility of the proposed scheme.

第37届中国控制会议

作者： Chengbao Zhou Lei Hou Yanfei Li Wenguang Yang North Information control Research Academy Group Co. Ltd. North Automatic control Technology Institute

The nonlinear attitude Kinematics of flexible spacecraft are expressed by the Euler angles and described by the vector form. Based on the dynamic surface control（DSC） approach, a robust adaptive nonlinear sliding mode attitude tracking algorithm is designed for flexible spacecraft in the presence of the external disturbances and system parameter uncertainties. This attitude control algorithm can be used when the upper bound of the lumped disturbances is unknown. Meanwhile the active vibration suppression control is adopted for flexible spacecraft. By the Lyapunov stability analyses, the designed algorithms can guarantee the stability of the spacecraft attitude tracking control system. With the modal velocity feedback（MVF） method, the undesirable vibration of the flexible appendages of spacecraft is in the active suppression. Finally, the control simulation analyses verified the effectiveness of the proposed control strategy.

Robust Adaptive Formation control of Underactuated Autonomous Underwater Vehicles Under Input Saturation

第30届中国控制与决策会议

作者： Jian Li Jialu Du School of Marine Electrical Engineering Dalian Maritime University

In this paper, we investigate the leader-follower formation control of underactuated Autonomous Underwater Vehicles（AUVs） in the presence of unknown bounded time-varying disturbances and input saturation, where the non-diagonal mass and damping matrices are considered in the realistic dynamical model of AUV. Additional control is employed to handle the input saturation and underactuation of AUV. Based on the additional control, the leader-follower formation control law is designed by incorporating adaptive technique with dynamic surface control（DSC） method. The adaptive laws are designed to estimate the bounds of unknown time-variant environmental disturbances. The stability analysis indicates that the proposed formation control law can make AUVs achieve the desired formation and guarantees uniformly ultimate boundedness of all signals of the AUVs formation closed-loop system. Simulation results on three AUVs demonstrate the effectiveness of the proposed formation control law.

第24届中国控制与决策会议

作者： Tianping Zhang, Baicheng Zhu and Xiaocheng Shi the Department of Automation, College of Information Engineering, Yangzhou University, Yangzhou 225127, P. R. China

In this paper, an novel adaptive tracking con- trol is developed for a class of completely non-affine pure- feedback nonlinear systems using radial basis function neural networks (RBFNNs). Combining the dynamic surface control (DSC) technique and backstepping method, the explosion of complexity in the traditional backstepping design is avoided. Using mean value theorem and Young’s inequality, only one learning parameter need to be tuned online in the whole controller design, and the computational burden is effectively alleviated. It is proved that the proposed design method is able to guarantee semi-global uniform ultimate boundedness (SGUUB) of all signals in the closed-loop system. Simulation results verify the effectiveness of the proposed approach.

作者： Luhuan Shi Tianping Zhang Meizhen Xia Qikun Shen Department of Automation College of Information Engineering Yangzhou University

In this paper, robust adaptive control problem is discussed for a class of output feedback nonlinear switched systems with unmodeled dynamics and time-varying constraints. Based on the common Lyapunov function(CLF), an adaptive output feedback dynamic surface control(DSC) scheme is developed. Radial basis function neural networks are utilized to approximate unknown continuous functions, and K-filters and a dynamic signal are designed to estimate the unmeasured states and deal with the dynamic uncertainty. An asymmetric barrier Lyapunov function(ABLF) is introduced to handle output constraint. It is proved that the designed controller can guarantee the semi-global uniform ultimate boundedness(SGUUB) for all the signals in the closed-loop system under arbitrary switchings. The simulation results are provided to demonstrate the effectiveness of the proposed method.
