Network-Based Reset Control Systems With Time-Varying Delays

Reset compensators have shown to have advantages over linear and time-invariant compensators, especially when used in control loops with time delays. In this work, the potentials of reset control in networked control systems are investigated. Specifically, stability conditions are developed for the case in which network-induced delays are time-varying. To this end, it is shown how a network-based reset control system may be represented as a discrete-time reset control system. In addition, both state-dependent and time-dependent discrete-time reset compensators are analyzed. Finally, a case study is developed and simulation results are discussed, showing the superior performance of reset compensation.
