Recall the example of a cruise control system for an automobile presented in Fig-ure 8.4. Sometimes an electronic system is also referred as “Control system”. The most simple example of a physical access control system is a door which can be locked, limiting people to one side of the door or the other. A negative feedback amplifier is designed by connecting the input signal to the inverting pin of the op-amp and connecting some … In electronic theory, a system can be said as a group of interconnected electronic devices, in which each individual system having its own input – output relation, to control the other block by connecting its output further to its next system. Because its rotor consists only of a coil winding with very low inertia, it can be accelerated or stopped very rapidly. “ The engineer’s first problem in any design situation is to discover what the problem really is. Modern voltage stabilizers utilize solid state electronic components which measure the fluctuation in voltage and reduce/increase (buck/boost) the voltage to the desired level. Each block in a control system will represent a system or an individual component of a system. The term is associated with core operational technologies that automate work, control equipment and provide data processing services. The rate of change of a control system with the change in its surroundings is called “Sensitivity”. In a simple electronic system, we have input and outputs in the form of signals. The thermostat senses the temperature of the system and maintains the temperature. This process is generally known as “Cause and Effect analysis”.
