Q2. What is equation of PID controller
Ans. 
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

Q1. How to measure pitch of ballscrew.
Ans. 
The pitch of a ballscrew can be measured by counting the number of threads per unit length.

• Count the number of threads within that distance.

• Divide the distance by the number of threads to calculate the pitch.

• Pitch = Distance / Number of threads
