| Popis: | 81 In this thesis, an optimal controller of periodic discrete -time and multirate systems is proposed. First, we transform a periodic time-varying system into many time-invariant subsystems and then perform the discrete LQG design. Moreover, the loop transfer recovery techniques at the input and the output of square minimum-phase discrete systems are considered and the feedback properties are obtained by the recovery techniques. Next, the optimal controllers with computation delays for the periodic discrete and multirate systems are obtained and some results are derived. Also, we derive the asymptotic sensitivity matrices by loop transfer recovery procedures. Finally, we consider the stationary LQG optimal regulation problem for systems with free measurements of white noise components. A simple direct expression for the optimal controller for linear discrete time-invariant right- or left- invertible systems in the z-domain is obtained. And we derive simple conditions for the precise recovery of the return-ratio matrix of the LQ regulator. |
