“…[9][10][11][12][13] Moreover, a partitioning strategy was put forward in Reference 5 to analyze the FTB cover the reaching and the sliding phases, respectively. This interesting results have been also extended to various complex systems including switched systems, 6 fuzzy systems, 7 and Markov jump systems. 8 However, it is worthy of noting that the aforementioned works include an implicit assumption, that is, the measured states/output signals are completely available for the designed controller for achieving the objective of FTB.…”

This article investigates the problem of sliding mode control (SMC) for continuous-time systems under the requirement of finite-time boundedness (FTB), in which the state signals are periodically sampled and transmitted to the controller according to the pre-designed event-triggering condition. A key issue is how to utilize the less available state information to achieve the FTB of the closed-loop system. To this end, the continuous-time SMC law is changed into an implementable form dependent on the available sampled state via event triggering transmission. It is shown that the state trajectory of the controlled system can be driven onto the specified sliding surface before the given finite time, and then, remain within a domain around this sliding surface. Due to the characteristic of the periodic event-triggered scheme (ETS), the known partitioning strategy on the SMC with FTB is infeasible for this present case. Instead, we shall analyze the FTB of the closed-loop system over the whole given time, meanwhile, a selection condition on the robust term is given via the given time parameter. Finally, the numerical simulation results are provided to illustrate the proposed periodical event-triggered SMC scheme.

“…Remark 5. It is easily shown that these conditions (8)- (9) in Theorem 1 can be ensured by conditions (36)-(37) of Theorem 2. Thus, if these conditions (10)-(12) and (36)-(37) are satisfied, it can be obtained from Theorems 1 and 2 that the closed-loop switched system (7) is exponentially stable with a prescribed weighted H ∞ performance.…”

“…Owing to the significance both in practical applications and theoretical research, switched systems have been widely investigated in many fields, such as robotics, power electronics, chemical processes, aircraft and air traffic control, etc, and lots of exciting results have been obtained on the stability and stabilization problems for switched systems in the past decade . Especially, sliding mode control (SMC) method, as an effective robust control technique, has been also successfully applied in uncertain switched systems, stochastic systems, and other systems . For example, the SMC problem was considered in the work of Wu and Lam for uncertain switched systems with the same control input matrices for all subsystems.…”

Summary This work considers the sliding mode control problem of a class of discrete‐time uncertain switched systems subject to detecting‐delay on mode signals, which may result in the asynchronous phenomenon between the controller and the switched system. Since the mode information of the controlled system is not available for the controller in time, a mode‐independent sliding surface will be introduced, by which an asynchronous sliding mode controller is designed, whose control gain and robust parameter will be changing according to the controller mode. In the analysis on the stability of the closed‐loop control system and the reachability of the specified sliding surface, the asynchronous characteristics are detailedly investigated. It is shown that the Lyapunov function may be not always decreasing along the state trajectories during the unmatched interval of controller modes and system modes. Nevertheless, it is proven that the state trajectories can be driven into a sliding region around the specified sliding surface in finite time. Finally, some numerical simulation results are provided.
