Nowadays, with the development of electronic technology, digital circuit or digital system can be seen everywhere in people’s life. Traffic lights are all over the streets and lanes. The main basis of the design of traffic light controller is digital electronic technology. When designing a digital circuit system, we must first define the design requirements

Aiming at networked control system (NCS) with time-varying delay, a new distributed event triggering communication mechanism is proposed. 　　This mechanism can effectively save network resources and does not depend on the complete information of the state data. Several spatial distributed sensor nodes collect local information of the state data and transmit signals according to the

In this paper, the dynamic performance of aero-engine acceleration process is improved by switching among several controllers, and it is protected when the speed is too high. Firstly, according to the aeroengine control system model, an H________________________ In order to avoid unnecessary loss of actuator caused by frequent switching, the safety protection controller and event
