Control Systems

Can you give me an example of control law, sensing mechanism and the actuation mechanism?

1 . Feedback Systems

1. Aircon

Sensing Mechanism : Thermometer Actuation Mechanism : Thermostat Wheel
Control Law : NA

1. Control Law : Cruise Control System

2. Sensing Mechanism: Light Dependant Resistor (LDR)

3. Actuation Mechanism: Electric Motors

Step-by-step explanation

1. In a cruise control system, the control law compares the reference speed to the current speed and uses this error in a PID control algorithm to determine the signal that is then sent to the actuators to decrease the error between the desired and actual speed.

2. Photoresistors, also known as light dependent resistors (LDR), are light sensitive devices most often used to indicate the presence or absence of light, or to measure the light intensity.

3. Any part of a piece of equipment or appliance that translates electrical energy into motion, such as those found in ventilation fans, blenders, or refrigerators, contains at least one actuator. Electric cars also use actuators.
