    A comparison of the Inverse Nyquist Array and Pole Assignment techniques
    (1989) Venzke, Rainer Horst Erich; Braae, Martin
    This dissertation compares the Inverse Nyquist Array (INA) and the Pole Assignment techniques in multivariable control system design. The representation of multivariable systems in both the frequency domain and state space is discussed. A laboratory flotation system, for which a model by step response analysis is derived, is used as a practical example for both methods. A detailed description of the theory of both techniques is given. Particular emphasis is given to how the theory can be applied with the use of a personal computer. Computer-aided control system design programs for the INA and Pole Assignment techniques are included. A complete feedback control scheme for the flotation rig is designed with the INA technique. Pole Assignment by state feedback is used to improve the speed of response of the rig. The implementation of a Kalman filter, which is required for the Pole Assigment technique, is also described.
