The EMM is developed on the basis of mechanical analogy of power system by using spring connected rod-inertia system. The proposed EMM introduces an imaginary spring for the analogical correspondence to the transfer conductance of a transmission line with discussion of its energy storage properties. The imaginary spring produces its forces acting on the both ends perpendicular to its displacement vector. The rod-inertia system is completely analyzed in order to show that it has just the same dynamic equations as the power system. The proposed EMM provides theoretical background for energy-based analysis of power systems, which enables us to utilize well-known theories such as Lagrange's equation.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

In a previous paper (Ong et al., 1984), the invertibility of a quantum system coupled to a weak time-dependent classical field was studied. The physical system is modeled as an infinite-dimensional bilinear system. Necessary and sufficient conditions of invertibility were derived under the assumption that the output observable is a quantum nondemolition observable (QNDO), characterized by the classical property that its expected value is equal to its measured value. In this paper necessary and sufficient conditions are developed for an observable to qualify as a QNDO; if in addition the criteria for invertibility are met, the given observable defines a quantum nondemolition filter (QNDF). The associated filtering algorithm thus separates cleanly into the choice of output observable (a QNDO) and the choice of procedure for processing the measurement outcomes. This approach has the advantage over previous schemes that no optimization is necessary. Applications to demodulation of optical signals and to the detection and monitoring of gravitational waves are envisioned.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

The objective is to maintain the relative distances between the vehicles close to their desired values. It is shown that the conditions under which the control law is well-defined depends on the choice of the reference frame and control inputs. These conditions in the case when the design is carried out in the body frame of the follower are more restrictive than those encountered in the case of the body frame of the leader. The control algorithm is based on a new error formulation in the inertial frame. A detailed analysis and control design procedure are presented.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.

The proposed method casts the problem of actuator and sensor selection as a convex optimization problem and which ensures that the resulting transfer function of the linear component becomes strictly positive real. Hence for an actuator and/or sensor whose dynamics have sector bounded nonlinearities, an application of Popov's/circle criterion with a simple static feedback would ensure absolute stability. Furthermore, the nonlinear extension is formulated using dynamic game theory under partial state information.","PeriodicalId":131411,"journal":{"name":"Proceedings of the 40th IEEE Conference on Decision and Control (Cat.
