Control Systems | Classification, Definition & Examples
A control system is a group of mechanical or electronic devices that uses control loops to control other devices or systems. Click to read more about Control Systems.
What is an example of an open loop control system?
So, the plant produces an output, which is controlled. The traffic lights control system which we discussed earlier is an example of an open loop control system.
How does an error detector work?
The error detector produces an error signal, which is the difference between the input and the feedback signal. This feedback signal is obtained from the block (feedback elements) by considering the output of the overall system as an input to this block. Instead of the direct input, the error signal is applied as an input to a controller.
What happens to output in a closed loop?
In closed loop control systems, output is fed back to the input. So, the control action is dependent on the desired output.
What is continuous time control?
Continuous time and Discrete-time Control Systems 1 Control Systems can be classified as continuous time control systems and discrete time control systems based on the type of the signal used. 2 In continuous time control systems, all the signals are continuous in time. But, in discrete time control systems, there exists one or more discrete time signals.
What is a control system?
A control system is a system, which provides the desired response by controlling the output. The following figure shows the simple block diagram of a control system.
Is the output of an open loop control system fed back to the input?
In open loop control systems, output is not fed-back to the input. So, the control action is independent of the desired output.
Is a control system continuous or discrete?
Control Systems can be classified as continuous time control systems and discrete time control systems based on the type of the signal used. In continuous time control systems, all the signals are continuous in time. But, in discrete time control systems, there exists one or more discrete time signals.
Thermostat Heater
The thermostat heater is an example of closed loop control system. The thermostat senses the temperature of the system and maintains the temperature.
Sunseeker solar system
Sunseeker solar system is an automatic tracker which uses LDR to sense the sunlight. A microcontroller reads the LDR voltage and signals the connected motor which rotates the panel towards the sun.
Voltage stabilizer
The voltage stabilizer stabilizes the supply voltage in case of fluctuations. 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.
Missile Launcher
A missile launcher detects the position of the plane using radar tracking unit and then
Auto Engine
The tachometer in auto engine generates a voltage proportional to the speed of the shaft. The voltage is subtracted from the input voltage to calculate an error voltage that provides information about current speed and desired speed. The error voltage is then used to arrange the throttle after amplification.
Inverter AC
The inverter air conditioner uses an inverter for controlling the compressor speed. Sensors measure the ambient air temperature and then adjust compressor to the required level.
Automatic toaster
The automatic toaster measures the temperature, moisture vs dryness level of toast and adjusts the heat setting of toasts.
What are the different types of embedded systems?
Embedded systems are subdivided into the categories: stand alone, real time, networked and mobile. All four types of embedded systems are in daily life.
What is embedded system?
Embedded systems refer to the use of software and electronics with a dedicated purpose within a larger system or product. Embedded systems are far more ubiquitous than the general-purpose computer found in almost every home. As such, there are many examples of embedded systems in daily life. Where can embedded systems be found?
Where can embedded systems be found?
Where can embedded systems be found? Electric toys, pacemakers, and electric stoves all contain embedded systems. Thus, even the computer illiterate interact with this technology, often unknowingly.
What is a programmable thermostat?
Thermostat - the programmable thermostat was a great addition for those who wanted to run their furnace or air conditioners more efficiently, but have the house comfortable upon their arrival home. Program the times you want the temperature to change and go about your daily routine.
Why is automation important in the office?
Having automation in your office allows you to focus more time on your clients and revenue generating tasks. If you could automate email sends, like email greetings or reminder emails, why wouldn’t you?
