The output feedback robust control design is required for switched systems (SSs) without the state feedback information. For the sliding mode control (SMC) based on state observers, the unmatched uncertainty and disturbance cannot be rejected completely. In this paper, an output feedback sliding mode control (SMC) based on a robust integral sliding mode (RISM) is presented for switched systems with unmatched uncertainties. First, the control task of the output feedback stabilization based on the state observer is given. Then, in order to reject the unmatched uncertainty, the RISM is constructed on the space of the estimated state, whose parameters are selected ensuring that the system in the sliding mode is robust exponentially stable. Linear matrix inequality conditions for the parameter design and the stabilization switching rule are achieved, which make the sliding mode can reject the unmatched uncertainty and suppress the unmatched disturbance both at the designed control switching rule and the arbitrary switching rule. Consequently, the corresponding SMC controller is designed based on the state estimation and the propsoed RISM. Finally, the application simulation results to a one-link manipulator with the load change validated the effectiveness and feasibility.INDEX TERMS Switched systems, unmatched uncertainty, sliding mode control, output feedback, integral sliding mode.

“…At present, various control methods of chaos system have been discussed, like sliding mode control [21], Backstepping control [22], active control [23], passive control [24], adaptive control [25], fuzzy control [26], etc. However, finite-time control of complex systems have attracted much attention due to their good robustness and anti-disturbance performance in recent decades [27][28][29].…”

As chaotic systems are widely used in many fields, the study of them is becoming more and more in-depth. This paper first presents a new single-equilibrium chaotic system which is only three terms, and some fundamental dynamical feature of the new chaotic system are discussed, such as equilibria, dissipativity, Poincaré diagram, bifurcation graph, etc. Secondly, a new finite-time controllers is designed by using Lyapunov stability theory, and it can be used for bound synchronization of the general chaotic systems. In contrast to the current finite time controller of the chaotic system, the designed controller in this paper does not contain exponential term, it can be simple and eliminate the chattering phenomenon during synchronizationis, which may be easier to implement in practical application. In addition, under the finite time controller, the bound of control energy consumption of the chaotic system is estimated. Finally, the finite-time controllers for the new chaotic system are advanced using the design method of finite-time controller of the general chaotic system, and the result of numerical simulation is given to check its validity by the designed method.
