Control Methods For Electrical Machines: A Handbook

Logic controllers may respond to switches, light sensors, pressure switches, etc., and can cause the machinery to start and stop various operations. Logic systems are used to sequence mechanical operations in many applications. Examples include elevators, washing machines and other systems with interrelated stop-go operations. Logic systems are quite easy to design, and can handle very complex operations. Some aspects of logic system design make use of Boolean logic. Applied contexts require that a candidate method for monitoring working memory load must not interfere with operator performance, must be employable across many contexts, and must have reasonably good time resolution.
