Closed-loop linear dispersion coded eigen-beam transmission and its capacity

Open-loop and Closed-loop Optimization of Linear Control Systems

A canonical optimal control problem for linear systems with timevarying coefficients is considered in the class of discrete controls. On the basis of linear programming methods, two primal and two dual methods of constructing optimal open-loop controls are proposed. A method of synthesis of optimal feedback control is described. Results are illustrated by a fourth-order problem; estimates of ef...

Identifiability of Linear Closed-loop Systems

Closed-Loop Measurement of Equipment Efficiency and Equipment Capacity

Formal definitions for the components of efficiency and capacity, mathematical formulas for computing overall efficiency, and data collection strategies are proposed for rigorous measurement of equipment efficiency and equipment capacity. Measurement of overall equipment effectiveness (OEE) under the TPM paradigm is revised to become a true quantitative measure of efficiency that we term overal...

Closed Loop Light Beam Micromanipulators for Optical Metrology

The use of light beam micromanipulators in space subsystems has received particular attention in recent years. To compensate for changes in system parameters during the flight, these devices require closed loop control. This paper reports on an integrated feedback mechanism devised for flexural tortional devices. It consists in using monolithically embedded photodetectors to measure the portion...

A Mixed Integer Linear Programming Model for the Design of Remanufacturing Closed–loop Supply Chain Network

Closed-loop supply chain network design is a critical issue due to its impact on both economic and environmental performances of the supply chain. In this paper, we address the problem of designing a multi-echelon, multi-product and capacitated closed-loop supply chain network. First, a mixed-integer linear programming formulation is developed to maximize the total profit. The main contribution...
