💡 Hint

Common Mistakes

Confusing Derivative with Differential or Discrete terms.

Thinking the third term is Dynamic, which is not part of PID.

The PID controller has three parts: Proportional, Integral, and Derivative. The Derivative term predicts future errors.

medium

Complete the formula to calculate the Proportional term output in a PID controller.

Power Electronics

Proportional output = Kp * [1]

💡 Hint

Common Mistakes

Using setpoint instead of error.

Confusing integral or derivative terms with proportional.

The Proportional term multiplies the error by the proportional gain Kp to produce its output.

3fill in blank

hard

Fix the error in the integral term calculation of the PID controller.

Power Electronics

Integral output = Ki * sum([1]) * dt

💡 Hint

Common Mistakes

Summing setpoint or output instead of error.

Using derivative instead of error in the integral calculation.

The integral term sums the error over time, multiplied by the integral gain Ki and the time step dt.

4fill in blank

hard

Fill both blanks to complete the derivative term formula in a PID controller.

Power Electronics

Derivative output = Kd * ([1] - [2]) / dt

💡 Hint

Common Mistakes

Using setpoint or output instead of error values.

Reversing the order of subtraction.

The derivative term calculates the rate of change of error by subtracting the previous error from the current error, divided by the time step dt, then multiplied by Kd.

5fill in blank

hard

Fill all three blanks to complete the PID controller output formula.

Power Electronics

PID_output = Kp * [1] + Ki * [2] + Kd * [3]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using setpoint instead of error terms.

Mixing up integral and derivative error terms.

The PID output is the sum of the proportional term (Kp times error), integral term (Ki times integral of error), and derivative term (Kd times derivative of error).
