热控专业英语

章节摘录

　　In recent years， automatic control systems have assumed an increasingly importantrole in the development and advancement of modern civilization and technology. Domesti-cally， automatic controls in heating and air conditioning systems regulate the temperatureand the humidity of modern homes for comfortable living. Industrially， automatic controlsystems are found in numerous applications， such as quality control of manufacturedproducts， automation， machine tool control， modern space technology and weapon sys-tems， computer systems， transportation systems， and robotics. Even such problems as in-ventory control， social and economic systems control， and environmental and hydrologicalsystems control may be approached from the theory of automatic control.　　The basic control system concept may be the simpleblock diagram shown in Fig. 1.1. The objective of the sys-tem is to control the variable c in a prescribed manner bythe actuating signal e through the elements of the controlsystem.　　In more common terms， the controlled variable is the output of the system， and the actua-ting signal is the input. As a simple example， in the steering control of an automobile， the direc-tion of the two front wheels may be regarded as the controlled variable c， the output. The posi-tion of the steering wheel is the input， the actuating signal e. The controlled process or system inthis case is composed of the steering mechanisms， including the dynamics of the entire automo-bile However， if the objective is to control the speed of the automobile， then the amount ofpressure exerted on the accelerator is the actuating signal， with the speed regarded as the con-trolled variable.
