Realization of finite-time robust speed tracking control for a micro-turbine as a distributed energy resource

In this paper, a finite-time robust speed tracking control law via output feedback is proposed for a single-shaft micro-turbine (MT) as a distributed energy resource. As a main contribution, a novel non-recursive design manner is employed in this paper to render a finite-time exact speed tracking result with tunable robust margin for the MT system. This approach will avoid heavy calculations of recursive partial differential terms which are inevitable by backstepping based methods and therefore, the controller now can be expressed as a very simple form. In addition, a sensor-less control strategy will clearly lead to a reliability improvement and an implementation cost reduction of the control system. Both theoretic analysis and numerical simulation results are presented to demonstrate the speed tracking performance of the proposed controller.
