So it's not necessarily cheating if it helps you learn too. A lag compensator decreases the bandwidth/speed of response: good to reduce the impact of high-frequency noise, bad if you want the system to react fast -> use lead compensator. Zeros have the opposite effect the closer your frequency puts you to a pole, the filter transfer function will decrease and vice-versa. If both fast responses and good static accuracy are desired, a lag-lead compensator may be employed. Think of poles as controlling a frequency-dependent feedback or resonancethe impulse response of a pole inside the unit circle decays, while one outside is like runaway feedback (think of a mic feeding back into a loudspeaker).
