摘要：
The computation of attitude control laws using Linear Quadratic Regulator/Loop Transmission Recovery (LQG/LTR) leads to classical compensators which contain sufficient pole-zero cancellation that can be reduced to the ratio of a real zero to a complex conjugate pole pair. Similar results follow for a 3-car train connected by springs. Controllers for a number of randomly generated dynamic systems also show this type of order reduction because closed loop dynamic systems are structurally Newtonian. The resultant closed loop LQG/LTR system with have the LQ generated poles as the dominant modes, but somewhat different eigenvectors.
