Dynamic Output Feedback Controller for a Harvested Fish Population System

摘要

This paper deals with the control of a continuous age structured model of a harvested fishery system, using a dynamic output feedback controller. In our case, the continuous fishery model is considered, where the effort is used as a control term, the age classes as a states and the quantity of captured fish per unit of effort as a measured output. Under some biological satisfied assumptions we formulate an observer and a controller to stabilize globally exponentially the closed loop Takagi Sugeno (T-S) model. The continuous non-linear model is first represented by a T-S model. Next, we develop a technique for designing a dynamic output feedback control law which globally stabilizes this fuzzy system model. The simulation results demonstrate the effectiveness of the proposed method.
