项目摘要

IN THE DESIGN OF THE FEEDBACK CONTROL SYSTEMS,THE LOWER SENSITIVITY IS REQUIRED FOR SMALL ERROR TO THE REFERENCE INPUT IN THE PRESENCE OF DISTURBANCES AND PERTURBATIONS OF THE PLANT.FOR THE ROBUST STABILITY,THE COMPLEMENTARY SENSITIVITY HAS TO BE SMALL.THE SENSITIVITY AND THE COMPLEMENTARY ONE CAN NOT DECREASE TO ZERO SIMULTANIOUSLY.TO OVERCOME THE DILEMMA,TWO DISK MIXED SENSITIBITY PROBLEM AND ROBUST PERFORMANCE ARE PROPOSED TO MAKE THE SENSITIVITY LOWER FOR LOW FREQUANCY AND THE COMPLEMENTARY ONE SMALLER FOR HIGH FREQUENCY.THE PURPOSE OF THE RESEARCH PROJECT IS TO PRESENT AN SYSTEMATIC DESIGN METHOD.INNER MODEL CONTROL APPROACH TO 2 DISK MIXED SENSITIVITY PROBLEM WAS PROPOSED AND SUBMITTDE TO IJC,1997. A SOLUTION TO ROBUST PERFORMANCE WAS PROPOSED BY USING STATE FEEDBACK CONTROL WITH OBSERVER AND FREE PARAMETER AND PRESENTED AT 2^<ND> ASCC.AN ITERATIVE SOLUTION TO 2 DISK MIXED SENSITIVITY PROBLEM WAS PRESENTED AND SUBMITTED TO SICE.FURTHERMORE,IT WAS POINTED OUT THAT THE CONTROL PERFORMANCE OF TIME DELAY SYSTEM CAN NO BE COVERED BY 2 DISK MIXED SENSITIVITY SPECIFICATION.THREE DISK MIXED SENSITIVITY PROBLEM AND ITS SOLUTION WERE PROPOSED AND PRESENTED AT 2^<ND> ASCC AND MATHEMATICS AND COMPUTATIONS IN SIMULATION.

在反馈控制系统的设计中,当设备存在扰动和扰动时,要求输入的灵敏度较低,以保证给定输入的误差较小。为了鲁棒稳定性,互补的灵敏度必须较小。灵敏度和互补的灵敏度不能太大同时降为零。为了克服这一困境，提出了两盘混合灵敏度问题和鲁棒性能，使低频和高灵敏度的灵敏度降低。高频补一小。本研究课题的目的是提出一种系统的设计方法。提出了解决2盘混合灵敏度问题的内模型控制方法，并提交给IJC,1997。提出了一种通过使用带有观察器和自由参数的状态反馈控制来实现鲁棒性能的解决方案，并在第 2^<ND> ASCC 上提出。针对 2 盘混合灵敏度问题的迭代解决方案已提出并提交给 SICE。此外，指出该控制时滞系统的性能不能被2盘混合灵敏度规范所覆盖。3盘混合灵敏度问题及其解决方案被提出并提出于 2^<ND> ASCC 以及数学和模拟计算。
