The controller can be implemented by an op-amp chip as shown in Figure 5 below. By using the op-amp and passive components such as resistors, inductors and capacitors, design the circuit of your controller that you have proposed Show the steps of your controller circuit design clearly. Draw the circuit diagram of your controller. Show all the components and values clearly in your circuit diagram. Explain how the circuit works.
