A grid-connected wind-energy converter system §including a matrix converter (MC) is proposed. Two §dynamic models are addressed: MC dynamic model, and §proposed wind turbine system overall model. The MC §dynamic model is valid for both steady-state and §transient analyses. In developing the system overall §dynamic model, individual models of the aerodynamic §conversion, drive train, MC, and induction generator §are developed. The constraint constant V/f strategy §is included in the final dynamic model. The model is §intended to be useful for controller design §purposes. The model dynamic behavior is investigated §by simulating the response of the overall model to §step changes in selected input variables. Moreover, §a linearized model is developed at a typical §operating point, and stability, controllability, and §observability of the system are investigated. Two §control design methods are adopted for the design of §the closed-loop controller: a state-feedback §controller and an output feedback controller. §Finally, a maximum power point tracking method, §referred to as mechanical speed-sensorless power §signal feedback, is developed for the system.
