“…For an affine nonlinear system with mismatched disturbances and uncertainties, a nonlinear disturbance observer-based robust control method was designed to compensate mismatched disturbances and uncertainties in a missile system in [19]. For a nonlinear system in a strict-feedback form with input quantization, actuator faults, and external disturbances, a fuzzy adaptive control scheme based on nonlinear disturbance observer was developed to solve the problem of adaptive fault-tolerant tracking control in a one-link manipulator in [20]. For an underactuated robotic system with matched and mismatched disturbances, a sliding mode controller based on high-order disturbance observer was presented to compensate matched and mismatched disturbances in [21].…”

For nonlinear coupled robotic system subject to matched and mismatched disturbances, this paper designs an adaptive disturbance observer-based exponential sliding mode controller to achieve position tracking. Firstly, matched disturbance, mismatched disturbance, and the derivative of mismatched disturbance are defined as the lumped disturbance in robotic system. Secondly, a nonlinear disturbance observer is constructed to estimate the lumped disturbance, and an adaptive law is proposed to estimate the bound of the lumped disturbance. Finally, an exponential sliding mode controller is derived by combining the nonlinear disturbance observer and exponential convergence law. Stability and tracking performance of the robotic system is analyzed via Lyapunov function approach. Simulation results show that, with the proposed approach, both matched and mismatched disturbances in robotic system can be effectively depressed while achieving position tracking.

“…The sliding-mode control methods were initiated in the former Soviet Union about 40 years ago, and since then the sliding-mode control methodology has been receiving much more attention within the last two decades. Sliding-mode control is widely adopted in lots of complex and engineering systems, including time delays [31][32][33] stochastic systems [34,35], singular systems [36][37][38], Markovian jumping systems [39][40][41], and fuzzy systems [42][43][44]. As is well known, system performance may be degraded by the affection of the presence of nonlinearities and external disturbances.…”

This paper is devoted to the investigation of the sliding-mode controller design problem for a class of complex dynamical network systems with Markovian jump parameters and time-varying delays. On the basis of an appropriate Lyapunov-Krasovskii functional, a set of new sufficient conditions is developed which not only guarantee the stochastic stability of the sliding-mode dynamics, but also satisfy the H ∞ performance. Next, an integral sliding surface is designed to guarantee that the closed-loop error system reach the designed sliding surface in a finite time. Finally, an example is given to illustrate the validity of the obtained theoretical results.

“…Nevertheless, most of the control systems are unable to meet the required performance due to the occurrence of the faults and affected by sensors or actuators. 14 So, the performance of the control system depends heavily on the quality of the sensor and actuator measurements. In particular, the problem of fault-tolerant control has been investigated for uncertain NCSs with induced delays and actuator saturation.…”

Summary In this paper, the robust reliable H∞ controller is designed for the problem of nonlinear actuator fault case in the uncertain networked control systems with randomly occurring missing data. More precisely, the occurrence of missing measurements is modeled by a stochastic variable in terms of Bernoulli random distribution. Also, the consideration of a nonlinear term in the input control scheme is a novel work for the proposed model. Suitable robust reliable design of control for a practical actuator fault model is constructed to guarantee the asymptotic stability of the system with H∞ performance level. A new form of Lyapunov‐Krasovskii functional with triple integral terms are formulated, and the reciprocally convex technique is utilized to establish the sufficient stability criterion in the form of linear matrix inequalities. Finally, the effectiveness of the proposed control method is shown through numerical examples, and we can confirm that the derived condition attained less conservatism than the existing results.
