Abstract :
The author (ibid., vol.36, no.9, pp.994-1007, Sept. 1991) formulated and solved an optimal linear quadratic Gaussian (LQG) problem for stability enhancement for flexible structures with collocated controllers and constructed an approximate realization of the compensator. An explicit closed-form solution for the compensator transfer function is obtained here. It is positive real but nonrational
