Design of robust control systems: equivalent system method

The paper is concerned with the problem of design of robust control systems preserving the stability and high performance under conditions of considerable uncertainty of the plant behavior. For solution of this problem the authors propose the equivalent system method based on construction and investigation of equivalent block diagrams of the control system, the output coordinate of which describes the additional motion of the explored system when its parameters are changing. The effectiveness of proposed design method is demonstrated by the example of design of a flight control system for a landing maneuver satisfying the given requirements with and without the presence of wind shear.<>
