Two Essays on Investment and Financing Decisions of Firms
… maximizing firm. This is an argument against the separation principle. The second important result is that dividend policy does generally affect the maximizing firm's value. This result invalidates the residual theory of dividends. The model prescribes an optimal investment-financing plan, the …

Dynamic power allocation and routing for satellite and wireless networks with time varying channels
… of such satellites is considered and a satellite separation principle is developed, demonstrating that joint optimal control can be implemented with separate algorithms for the downlinks and crosslinks.

Linear-time invariant Positive Systems: Stabilization and the Servomechanism Problem
… also encompass the two problems of the positive separation principle and stabilization via observer design. The second, and most emphasized, problem of this dissertation considers the positive servomechanism problem for both single-input single-output (SISO) and multi-input multi-output (MIMO) …

On Observer-Based Control of Nonlinear Systems
… are used in numerous applications. The feedback principle is an important concept in control theory. Many different control strategies are based on the assumption that all internal states of the control object are available for feedback. In most cases, however, only a few of the states or some …

Environmental Tracking and Formation Control for an Autonomous Underwater Vehicle Platoon with Limited Communication
… design are complicated by the lack of a separation principle for decentralized systems and by the effects of intervehicle coupling. The potential for choosing the communication topology in a manner that leads to design simplifications is investigated. In particular, a transformation is …

NONLINEAR OBSERVER/CONTROLLER DESIGNS FOR SPACECRAFT ATTITUDE CONTROL SYSTEMS WITH UNCALIBRATED GYROS
… in this case. There is, in general, no "separation principle" for nonlinear systems, as there is for linear systems. However, Lyapunov analysis of the coupled controller-observer dynamics shows that the closed-loop system will be stable for the class of observers proposed. With only gyro …

Uniform positive recurrence and long term behavior of Markov decision processes, with applications in sensor scheduling
… the system is stabilizable, we use a partial separation principle to transform the problem into an MDP on the set of symmetric, positive definite matrices. A special case of these results generalizes a known result for Kalman filters with intermittent observations to the multiple-sensor case, …

Active fault-tolerant control of nonlinear systems with wind turbine application
… Additionally, a proposal to recover the Separation Principle has also been developed via the use of TSDOFC within the FTTC framework.• The proposals of two FTTC strategies based on the estimation and compensation concept for sustainable OWTs control. The proposals have introduced a …

Machine Learning Aided Decision Making and Adaptive Stochastic Control in a Hierarchical Interactive Smart Grid
… signals from different customers. Based on the separation principle in reference prediction and tracking design, we propose both centralized and distributed reference prediction schemes based on Kalman filtering technique. In the forth part, with the hierarchical architecture well developed, the …

Simultaneous state and input estimation with applications in vehicle problems
… behaviour. A central paradigm in control is the separation principle, that is the optimal control action is achieved by applying the control law that is optimal under an assumption of full information to an “optimal estimate” of the system state. While in the context of linear-quadratic problems …
