Abstract
This paper presents the dynamic integral sliding mode control (DISMC) design for interconnected power systems (IPSs). The IPSs consider the effect of time delay related to area control error and the parametric uncertainty. Different from the previous studies, to fully adopt the characteristics of both the system state and control input vector, a novel type of integral sliding surface is defined. Also, a DISMC is designed to assure the system trajectories onto the predefined integral sliding surface despite uncertainties and disturbance. Linear matrix inequality (LMI)-based stabilization criteria are derived for resulting sliding mode dynamics with H∞ performance. Besides that, the control gains and sliding surface matrix are determined. Finally, a numerical example is given to demonstrate the effectiveness and feasibility of the developed DISMC design method.
