Gain scheduling adaptive control strategies for HVDC systems to accommodate large disturbances

Adaptive control of time-varying systems with gain-scheduling

“…It is shown that by augmenting a gain-scheduling controller with an adaptive controller, the desired behavior of the original nonlinear closed-loop dynamics can be achieved, if the gain-scheduled variable changes sufficiently slowly. In [7], adaptive gain-scheduling controllers are proposed for HVDC systems, where in simulations it is shown that they result in a better performance. In this paper, a formal description to construct an adaptive gain-scheduled controller is provided as well as stability analysis for nonlinear flight dynamics.…”

Design of a New Nonlinear Fuzzy State Feedback Controller for HVDC Systems

“…However, the advanced techniques available in DC adaptive control literature are difficult to apply in practical applications because of the absence of insight into performance with large disturbances, where the adaptive control may be not only ineffective but may degrade the performance rather than enhance it [2], [3]. A gain scheduling adaptive control strategy has been tried in [4] where the effect of large disturbances has been taken into account. In [5], the advantages of automatic continuous fine tuning are combined with predetermined gain scheduling in order to achieve robustness during large disturbances.…”

Damping controller design for FACTS devices in power systems using novel control techniques

“…An LPV gain-scheduling technique has been successfully applied in many engineering applications such as flight and process control [43,44,45,46], In [47], the LPV technique has been successfully used in the design of PSS's in two typical power systems. In [48], the gain-scheduling controller design method is suggested and successfully used in developing an HVDC control strategy.…”
