摘要：
Aiming at the longitudinal motion control of the large aircraft such as the stability requirements, disturbance rejection performances, system bandwidth limitation, altitude maintenance and tracking performances, we propose a control strategy using structured H∞ control. The theory proposed in this paper can maintain the benefits of the traditional H∞ synthesis theory, taking multiple performance requirements into consideration comprehensively, and design the structure of the controller according to the actual demand, it ensuring the controller a low order and complexity. It took Boeing series aircraft as an example, and designed a structured H∞ controller satisfying the integrated design objectives. Also, it verifies the performance of the control design by simulation analysis and the results show that the structured H∞ controller designed in this paper has a better tracking and stability performance. The design idea of the structured H∞ controller in this paper is a reference for other controller design of general systems, and the selection method of the weight function is a design example for other structured H∞ controller design. © 2020, Harbin University of Science and Technology Publication.
