Systematic H = weighting function selection and its application to the real-time control of a vertical take-o! aircraft

چکیده
In this paper, the selection of H = weighting functions for general practical applications is investigated. It is shown that an H = weighting function for a single-input}single-output (SISO) plant can be obtained by considering a series of connections of elementary low-order plants. For a constrained control e!ort, an explicit weighting function expression is derived for the "rst time. A novel method for the selection of weighting functions in H = mixed sensitivity design is proposed to control the percentage overshoot directly. An example illustrating how the transient response of a standard H = design is improved by using the proposed weighting functions is provided. Finally, real-time experimental results are presented for the roll-angle control of a laboratory-scale physical model of a vertical take-o! aircraft. ( 2000 Elsevier Science Ltd. All rights reserved.

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...
