Closed loop:
1. Thermostat --> furnace (constant temperature)
2. Toaster setting (light/dark) --> toast (IF the toaster has heat sensors)
3. Refrigerator cold/hot setting --> refrigerator inside temperature (constant)
4. Temperature setting for oven (not stovetop) --> oven temperature constant
5. Clothes dryer with moisture sensor
6. Washing machine water level
Furnace.
Temperature sensors control when furnace is turned on. Heating sensors in furnace control when air blower is turned on, and when flames must be turned off.
Refrigerator.
Temperature sensors control when refrigerant cycle turns on and off.
Many TV functions, internal operation of disc playback and record, really ad infinitum.

What are the two types of hydraulic systems?
The two types of hydraulic systems are open-loop and closed-loop systems. Open-loop hydraulic systems operate without feedback, meaning they do not monitor or adjust the flow based on output conditions. In contrast, closed-loop hydraulic systems utilize feedback mechanisms to continuously adjust and optimize the flow and pressure, ensuring more precise control and efficiency. Each system has its specific applications depending on the required level of control and complexity.
What is the difference between a hydrostatic and a hydraulic system?
By "Hydrostatic" systems one tends to mean "closed loop hydraulic systems". That is hydraulic systems comprising a pump and motor hwere the pump supplies the motor whose return side supplies the pump. The speed and direction of rotation of the hydraulic motor being changed according to the displacement angle of the variable displacement axial pison pump. "Open loop hydraulic systems" on the other hand comprises various motors often one or more "linear motors" (hydraulic cylinders). When using hydraulic cylinders in hydraulic systems one needs a reservoir to be able to hold the various volume need of the cylinder. (the displacement on the piston side is usually bigger than the rodside). The reservoir needs a "breather" due to the varous displacement needs hence the "open system".
What is servo drive?
A servo drive is any motor controller which uses a closed feedback loop to monitor the motors speed. This is normally accomplished through the use of an encoder or resolver.
Can a valve be installed at the end of steam expansion loop?
Yes. The expansion loop is only there to take up the thermal expansion of the pipe run, installing a valve will not impede the action of the loop.

How many types hydraulic systems there?
There are primarily two types of hydraulic systems: open-loop and closed-loop systems. Open-loop hydraulic systems operate without feedback and are typically simpler, used in applications where precise control is not critical. Closed-loop systems, on the other hand, incorporate feedback mechanisms for improved control and efficiency, making them suitable for applications requiring precise movement and pressure regulation. Additionally, hydraulic systems can be classified based on their design, such as single-acting and double-acting systems.
What is the difference between an open and closed loop engine management system?
An open loop engine management system operates without feedback from the engine's performance, relying on pre-set parameters to control fuel delivery and ignition timing. In contrast, a closed loop system uses feedback from sensors (such as oxygen sensors) to continuously adjust these parameters for optimal engine performance and emissions control. This feedback mechanism helps closed loop systems adapt to changing conditions, improving efficiency and reducing pollutants. Overall, closed loop systems are generally more precise and efficient compared to open loop systems.
Examples of the open loop system?
The system without feedback is known as open loop system. The examples of the open loop system are bread toaster, oven ,washing machine. The open loop systems are inaccurate & less complex.
Why is it necessary for circuits to maintain a closed loop?
Circuits need to maintain a closed loop to allow the flow of electric current. If the loop is broken, the current cannot flow, and the circuit will not work. This is essential for the proper functioning of electrical devices and systems.
What are the two types of hydraulic systems?
The two types of hydraulic systems are open-loop and closed-loop systems. Open-loop hydraulic systems operate without feedback, meaning they do not monitor or adjust the flow based on output conditions. In contrast, closed-loop hydraulic systems utilize feedback mechanisms to continuously adjust and optimize the flow and pressure, ensuring more precise control and efficiency. Each system has its specific applications depending on the required level of control and complexity.
What is a closed loop system?
A control system that appears to be self-regulating. Closed-loop systems employ feedback and a reference of correctness (norm or set point). Deviations from the norm are detected and corrections made in order to maintain a desired state in the system. Closed loop systems provide the homeostatic mechanism of many physiological functions (see negative-feedback) and also control some movement patterns, where feedback from proprioceptors and other receptors play an important part. Compare open-loop-system.
What is better an open-loop or closed-loop in a water craft?
The choice between an open-loop and closed-loop cooling system in a watercraft depends on the specific application and operating conditions. Open-loop systems use water from the environment for cooling and are typically simpler and lighter, making them suitable for smaller vessels. In contrast, closed-loop systems recirculate coolant, offering better temperature control and protection from contaminants, which can be beneficial for larger or high-performance crafts. Ultimately, the decision should consider factors like maintenance, environmental impact, and operational efficiency.
What is the difference between finite open loop gain and closed loop gain?
In a closed loop system the gain without the feed back loop being closed is called open loop gain!!! e.g if forward gain is "A" and feed back factor is "B" then open loop gain is "AB" and closed loop gain will be [A/(A+B)]
