Open loop does not have feedback mechanism, while closed loop does.

• Open loop system does not have a feedback mechanism to adjust the output based on the input.

• Closed loop system uses feedback from the output to control the input and maintain desired output.

• Open loop systems are simpler and less accurate, while closed loop systems are more complex but more accurate.

• Example: A toaster is an open loop system as it does no...read more

The equation of a PID controller is a control loop feedback mechanism used in industrial control systems.

• The equation for a PID controller is: u(t) = Kp*e(t) + Ki*∫e(t)dt + Kd*de(t)/dt

• Kp, Ki, and Kd are the proportional, integral, and derivative gains respectively

• The proportional term Kp reacts to the current error value

• The integral term Ki reacts to the accumulation of past errors

• The derivative term Kd reacts to the r

Two common pressure sensors are piezoresistive sensors and capacitive sensors.

• Piezoresistive sensors: measure pressure by changes in electrical resistance

• Capacitive sensors: measure pressure by changes in capacitance

Open loop does not have feedback mechanism, while closed loop does.

• Open loop system does not have a feedback mechanism to adjust the output based on the input.

• Closed loop system uses feedback from the output to adjust the input and maintain desired output.

• Examples of open loop systems include a toaster or a washing machine with a timer setting.

• Examples of closed loop systems include a thermostat controlling room temper
