Abstract |
|
|
| n this paper, we present an example of control system design based on negative imaginary (NI) system theory. The system
under consideration is an optical cavity system. A dynamical model of the cavity system is obtained through system identification of
applied to experimental input output frequency response data obtained using a digital signal analyzer (DSA). The identified model
satisfies NI property. An integral resonant controller is designed based on the NI system theory. |
