Minimum Variance Control

This paper presents a comparative analysis regarding a self-tuning minimum variance control system of a double-fed induction generator with load and connected to a power system through a long transmission line. A new complex nonlinear model describing this relationship between the induction generator, electrical consumer, transmission line, and power system is designed and implemented to simulate the controlled plant behavior. Starting from a simplified linear model of this complex plant, obtained through linearization of its nonlinear model around an operating point, the minimum variance control law design is performed by minimizing a cost criterion function. The main goal and also the paper novelty consists of the identification of a minimum order of this linearized model used to design a reduced order control law, which can still provide good control performance.

The weighted minimum variance control is extended to include the rational transfer function as well as the polynomial as the weighting on system input energy so as to guarantee the closed-loop stability in the whole range of the scalar input cost and the monotonic property of the controlled output and control input variances with respect to the scalar input cost. In addition, the Robbins-Monro scheme is modified for on-line adaptation of the scalar input cost under the time varying external disturbance to satisfy the constraint on input variance. The two schemes are then combined and applied to the vibration control of a servo-damper beam system. The experimental and simulation results show that the maximum usage of the available input energy is ensured in the presence of time varying external disturbance so as to achieve the good control performance and the effectiveness of the servo-damper system used for the suppression of the beam vibration.
