Q1. 1. how is motor connected to PLC 2.use of PID controller 3. which motor is used in fans 4. Inrush current 5. Is starting current more or running current
Ans. 
Motor is connected to PLC using motor starters or variable frequency drives. PID controller is used for precise control. Fans typically use induction motors. Inrush current is the initial surge of current when a motor starts. Starting current is usually higher than running current.

Q1. What is polymorphism in C++?
Ans. 
Polymorphism in C++ allows objects of different classes to be treated as objects of a common superclass.
• Polymorphism is achieved through virtual functions and function overriding.

• It allows for more flexibility and extensibility in code.

• Example: A base class 'Shape' with virtual function 'draw', and derived classes 'Circle' and 'Square' that override 'draw'.

Q2. Explain how different kind of motions are achieved in a Drone
Ans. 
Different motions in a drone are achieved through varying the speed and direction of the propellers.
• Changing the speed of the propellers controls the altitude of the drone.

• Varying the speed of propellers on different sides of the drone allows it to move forward, backward, left, or right.

• Adjusting the speed of the propellers diagonally creates rotational motion for turning.

• Combining these motions enables the drone to pe

Q4. Explain PID controller and its tunning.
Ans. 
PID controller is a control loop feedback mechanism used in systems to control process variables.
• PID stands for Proportional, Integral, Derivative.

• Proportional term responds to the current error.

• Integral term corrects the accumulated error over time.

• Derivative term predicts future error based on current rate of change.

• Tuning involves adjusting the three parameters (P, I, D) to achieve desired system response.

• Example: I...read more
