本文探讨了多变量系统鲁棒稳定性和鲁棒对角优势的关系,得出了系统鲁棒对角优势保证系统鲁棒稳定的一般性结论,提出了一种鲁棒系统的设计方法,并在IBM微机上实现了计算机辅助设计,用该方法对大型加热炉控制系统进行了设计,结果表明,设计的系统具有鲁棒稳定性和良好的性能鲁棒性。 In this paper, we discuss the relationship between the robust stability of multivariable systems and the robust diagonal dominance, and give the general conclusion that robust robust stability of system robust diagonal advantage guaranteed system. A robust system design method is proposed. The computer aided design was implemented on the IBM microcomputer. The design of a large heating furnace control system was carried out with this method. The results show that the designed system has robust stability and good performance robustness.
