Finite‐time H∞ bumpless transfer control for switched systems: A state‐dependent switching approach

“…Specifically, when a switch occurs, the gains of switching controllers are different on both sides of switching points, which may result in discontinuity or even large jump of input value at switching points . In practice, the requirement upon reducing bumps of input value is necessary for better transient behavior and is referred to as bumpless transfer . The concept of bumpless transfer is introduced for conditional control algorithm in the work of Hanus et al where the discrepancy between the actual input and the desired output are considered.…”

“…19,20 In practice, the requirement upon reducing bumps of input value is necessary for better transient behavior and is referred to as bumpless transfer. [21][22][23] The concept of bumpless transfer is introduced for conditional control algorithm in the work of Hanus et al 24 where the discrepancy between the actual input and the desired output are considered. In the work of Turner and Walker, 25 a flexible LQ bumpless transfer control strategy is established for nonlinear systems.…”

“…Moreover, DOBC methods are extended to the attenuation of both the matched disturbances and mismatched disturbances . Furthermore, some DOBC methods are proposed to attenuate and reject the disturbances for stochastic Markovian jump system . In addition, the DOBC methods have also been applied to various engineering systems, such as unmanned helicopter system, DC motor system, servomechanisms system, underwater robot system, distillation column system, and so on.…”

“…22,23 Furthermore, some DOBC methods are proposed to attenuate and reject the disturbances for stochastic Markovian jump system. 24,25 In addition, the DOBC methods have also been applied to various engineering systems, such as unmanned helicopter system, 26 DC motor system, 27 servomechanisms system, 28 underwater robot system, 29 distillation column system, 30 and so on.It is well known that all the aforementioned DOBC methods compensate the total disturbances uniformly, which implies that all of the disturbances are removed by disturbance rejector. 20,31,32 However, some disturbances may play positive roles in improving control performance, which means that these disturbances have beneficial effects on the control system.…”

Feedback passification of switched stochastic time‐delay systems with multiple disturbances via DOBC

“…The average dwell-time (ADT) or mode dependent average dwell-time (MDADT) plays an important role in designing a restricted and time-dependent switching signal. [34][35][36][37][38] In addition, time delays generally describe propagation phenomena, material, or energy transfer in intercommoned systems and data transmission in communication systems. 39,40 They have been the main sources inducing oscillations, instability, and poor control performances.…”
