51Controllability — is an important property of a control system, and the controllability property plays a crucial role in many control problems, such as stabilization of unstable systems by feedback, or optimal control. Controllability and observability are dual… …
52Cost of poor quality — (COPQ) or poor quality costs (PQC), are defined as costs that would disappear if systems, processes, and products were perfect. COPQ was popularized by IBM quality expert H. James Harrington in his 1987 book Poor Quality Costs.[1] COPQ is a… …
53State space (controls) — In control engineering, a state space representation is a mathematical model of a physical system as a set of input, output and state variables related by first order differential equations. To abstract from the number of inputs, outputs and… …
54Distributed parameter system — A distributed parameter system (as opposed to a lumped parameter system) is a system whose state space is infinite dimensional. Such systems are therefore also known as infinite dimensional systems. Typical examples are systems described by… …
55Farfisa — is a manufacturer of electronics based in Italy. The Farfisa brand name is commonly associated with a series of compact electronic organ, and later, a series of multi timbral synthesizer. At the height of their production Farfisa operated 3… …
56Holonomic — In mathematics and physics, the term holonomic may occur with several different meanings. Contents 1 Holonomic basis 2 Holonomic system (physics) 2.1 Transformation to general coordinates …
57electric motor — motor (def. 4). [1885 90] * * * Introduction any of a class of devices that convert electrical energy to mechanical energy, usually by employing electromagnetic phenomena. Most electric motors develop their mechanical torque by the… …
58controllability concept — The principle that managers should only be held responsible for controllable costs and controllable investment. This concept is often difficult to apply in practice. Many costs are not easily classified as either controllable or uncontrollable… …
