中文摘要
      本文基于多变量系统奈氏阵列设计方法和鲁棒对角优势保证系统鲁棒稳定的结论，提出一种多变量系统鲁棒设计方法，该方法设计的鲁棒预补偿器使广义对象在一定摄动范围内严格符合鲁棒对角优势定义，因而系统一定是鲁棒稳定的。该方法具有保守性小，设计的控制器简单，易于工程实现等优点。用该方法对一参数不确定性工业对象进行了鲁棒系统设计，结果令人满意。
英文摘要
      Based on Nyquist Array method of multivariable system and the conclusion that robust diagonal dominance of a system guarantees its robust stability, a robust design method for multivariable system is presented in this paper. The robust precompensator which is designed by this method makes the generalized plant to conform the definition of robust diagonal dominance strictly within some perturbed range, so system is certainly stable. The method has advantages of less conservatism, simple controller and easy to implement in engineering. The results of robust design for an industrial plant with parameter uncertainty are satisfactory.
