  • Q1. What is PID control?
  • Ans. 

    PID control is a feedback control mechanism used in automation systems to regulate a process variable.

    • PID stands for Proportional-Integral-Derivative.

    • It continuously calculates an error value by comparing the desired setpoint with the actual process variable.

    • The controller then adjusts the control output based on the error value and the proportional, integral, and derivative gains.

    • Proportional control provides an outpu...
