Industry over the last two to three years has put a lot of effort into implementing Process Safety Metrics. This is a good practice but, now that we have metrics data, how are we utilizing them to improve process safety performance? Air Products has

A methodology is presented for the adaptive control of a single-input single-output system using the numerically stable method of singular value decomposition (SVD) for identification. This methodology is suitable for industrial applications where th

Typical areas with which systems science is concerned, such as biological, behavioral, and social processes, transportation, urban and environmental studies, involve the development of mathematical models of the underlying processes. In general, the

The application of quadratic programming to the design of digitally compensated control systems is described and illustrated with three examples. Previous papers (1, 2) discuss in detail the application of linear programming to the design of digitall

Quadratic programming is applied to the statistical design of sampled-data feedback control systems with finite impulse response time. Given a fixed plant, quadratic programming is used to determine the compensator which minimizes the mean-square sam

The mechanization of a gimballess inertial system for space navigation is considered. An error analysis reveals that the errors contain both sinusoidal and diverging components. Error damping methods are proposed and it is shown that damping can be a

Inertial navigation systems usually use gyroscopes to sense angular motion and use accelerometers to sense linear acceleration. It is feasible, however, using only linear accelerometers as sensors, to determine both the angular velocity and the linea

The human centrifuge is used to train pilots and astronauts for flights where they are subject to large accelerations. This paper deals with the problems of simulating such linear accelerations with a rotating device and presents suitable means of re

Three orthogonalization techniques to correct errors in the computeddirection cosine matrix are introduced. One of these techniques is avectorial technique based on the fact that the three rows of a directioncosine matrix constitute an orthonormal se
