Softcover. Condición: very good. Time-Lag in a Control System: "It often happens in physical experiments and in technical processes that there is some physical quantity, subject to random disturbances, which it is required to keep as nearly constant as possible by the operation of some controlling gear. For example, it may be required to keep a room, or a reaction vessel, at a constant temperature by controlling the electric current passing through a heating coil, or steam passing through heating pipes, or the operation of a heating or cooling engine. The operation of the controlling gear could be by trial and error, but it may often be desirable that it shall be made to depend in some definite way on the behaviour of the physical quantity to be controlled (controlling gear); and the apparatus employed (control apparatus). The two together comprise the Control System." No. 756. Volume 235. pp. 415-444. Co-authored by: A. Callender of the Research Department, I.C.I (Alkali) Limited, D.R. Hartree, F.R.S. and A.
