Example Of Sequential Control System

Pressing the up button gives the television an input telling it to switch to the next channel above the one it is currently receiving.

Example of sequential control system. A familiar example of a device with sequential logic is a television set with channel up and channel down buttons. There are various types of control systems but all of them are created to. A small numbers of oscillation or constant oscillation of output tend to indicate the system to be stable. Types of control systems.

During this time the other two lights will be off. 3 sequential control. Traffic lights control system is an example of control system. Setpoints are not limited to temperature.

For example various electric and pneumatic transducers may fold and glue a cardboard box fill it with product and then seal it in an automatic packaging machine. Sequential control system a control system in which the individual steps are processed in a predetermined order progression from one sequence step to the next being dependent on defined conditions being satisfied. Conveyor systems robots power protection systems motor startingandcontrol. They might for example carry out a series of read or write operations arithmetic operations or assignments to variables.

The duct static pressure sensor controlling fan speed will also have a setpoint. The control system evaluates this condition against the setpoint value. It is the time taken by the control system to achieve its stable output. A good control system possesses high speed.

Here a sequence of input signal is applied to this control system and the output is one of the three lights that will be on for some duration of time. In sequential order until reaching the end of the module s program where the module is either. The sequence control structure is the simplest of the three fundamental control structures that you learned about here. The transient period for such system is very small.
