Closed loop control systems tend to oscillate due to instability in the system caused by the presence of excessive gain or phase lag. When the gain or phase lag is too high, it can result in the system becoming over-compensated, leading to oscillations as the system tries to correct itself. Tuning the system parameters, such as gain and phase, is essential to prevent oscillations in a closed loop control system.
A system is considered a closed system when no mass crosses its boundaries, while a control volume is an open system where mass can enter or leave.
For a system to oscillate, it must have both inertia (resistance to change in motion) and a restoring force (a force that brings the system back to its equilibrium position after being displaced). These two properties are necessary for the system to oscillate back and forth around a stable equilibrium point.
In a closed system, pressure flows from high to low due to the natural tendency of gases or fluids to move from areas of higher pressure to areas of lower pressure in order to reach equilibrium.
The tendency for objects to change is known as entropy, a measure of disorder within a system. Over time, this tendency leads to the spontaneous increase of randomness and disorganization in a system.
Momentum is constant in a closed system when there are no external forces acting on the system.
closed loop system
Yes it is
A system is considered a closed system when no mass crosses its boundaries, while a control volume is an open system where mass can enter or leave.
The closed loop control refers to a system whereby an input forcing function is usually determined in part by the system response.
stability and repeatability
A Closed loop system basically will have a feedback which enables the rectification of the error in the main process,whereas it is not possible in an open loop system
yes
A closed system is termed as a control mass because it does not exchange mass with its surroundings. This means that no mass enters or leaves the system, and therefore the total mass within the system remains constant. This allows for the analysis of the system's energy changes and thermodynamic processes in isolation, making it a control mass for studying energy transfers and conservation.

I assume a "standing fan" is just a fan that moves air. It might have a few settings such as oscillate or slow, medium, fast for the fan speed. This is an open loop control system. There is nothing telling a controller that the fan is oscillating or not, nor is there a mechanism that is telling the fan that it is on slow, medium or high. If the fan were to have a temperature sensor on it that would apply power if the temp went above the preset limit, this could be described as a closed loop system.
