Abstract
Authors' summary: ``The controllability and observability of linear stationary multivariable control systems is investigated in the frequency domain. If the minimal polynomial of the system is of maximum degree, then a simple test involving mode cancellations determines controllability [observability]. For the general case, a simple test based on a partial fraction expansion yields the necessary and sufficient conditions for controllability [observability].''
