These instructional objectives provide you with a guide for learning the course material. During the examination you should be able to:

1. Explain the difference between first- and second-order transient system responses with and without feedback
2. Explain the effect controller gain has on system output for first- and second-order systems
3. Calculate the output and/or transfer function of a system with feedback and a disturbance
4. Calculate $\tau$ for first-order systems with feedback
5. Calculate the steady state value for first- and second-order systems with feedback and a disturbance, given a step input
6. Calculate $\zeta$ and $\omega_n$ for 2nd order systems with feedback and disturbances if the controller is P, PD, or PID
7. Calculate the steady-state output of a system given a step input and a P, PD, or PID controller
8. Describe the effect a P, PD, or PID controller has on the system response
9. Define and calculate open-loop gain, loop gain, open-loop transfer function, and closed-loop transfer function
10. Calculate steady-state error for a system with or without a disturbance for any input
11. Generate a magnitude and phase plot given a transfer function
12. Calculate magnitude and phase of a transfer function given a frequency
13. Convert magnitude from normalized to dB and vice versa
14. Read values from a magnitude and phase plot
15. Describe how feedback affects the magnitude and phase plots of a system
