Knowledge is power

Leverage New Knowledge to Avoid Being Blindsided

The idea that knowledge is power, coupled with the massive amount of information available to all of us today, should mean everyone should be powerful. Never before in human history has so much information been available. Movable type and the printing press in 15th-century Europe is generally considered the first “information revolution,” followed by the […]

An Overview of the Control Loops for Batch, Fed-Batch and Continuous Reactors

Nearly all reactors have temperature and pressure control since these affect reaction rate. Concentration control is desirable but depends upon the feasibility, accuracy, and reliability of analyzers and inferential measurements. For at-line analyzers, there is the additional consideration of the dead time added to the loop. To date offline analyzers have only been used to […]

Static Feedback Stabilization of Nonlinear Systems

Abstract: This paper considers a single sensor and single actuator approach to the static feedback stabilization of nonlinear systems. This is essentially a remote control problem that is present in many engineering applications. The proposed method solves this problem that is less expensive to implement and more reliable in practice. Significant results are obtained on […]

Bi-Objective Redundancy Allocation Problem

Abstract: Traditionally, in the redundancy allocation problem (RAP), two general classes of optimization problems are considered; reliability optimization and availability optimization. Contrary to reliability optimization, fewer researchers have studied availability optimization to find out the optimal combination of components type and redundancy levels for each subsystem in a system for maximizing (or minimizing) the objectives. […]

Leveraging Industry Silos to Develop New Business Opportunities

There has been a great deal of discussion about isolated silos in industry creating barriers to growth, but they also offer opportunities for those willing to take the initiative. The term silo thinking is used in business to describe the mindset when departments do not share information and collaborate with others in the same company. […]

Integrating DCS I/O to an Existing PLC

At the NASA Glenn Research Center (GRC) in Cleveland, Ohio, existing programmable logic controller (PLC) input/output (I/O) was replaced with distributed control system (DCS) I/O, while keeping the existing PLC sequence logic. Until about the year 2000, the GRC’s central process system (CPS) distributed control system used PLC I/O to remotely control and monitor process […]

Finite-Time Control for Nonlinear Spacecraft Attitude

Abstract: In this paper, a fast terminal sliding mode control (FTSMC) scheme with double closed loops is proposed for the spacecraft attitude control. The FTSMC laws are included both in an inner control loop and an outer control loop. Firstly, a fast terminal sliding surface (FTSS) is constructed, which can drive the inner loop tracking-error […]
