Problem 4a -- Change gain crossover to bandwith
Problem 4a states that you should find a proportional controller that has a gain crossover of at least 1 rad/sec. A proportional controller alone is not sufficient to meet this requirement. You should, instead, satisfy the requirement that the bandwidth exceed 1 rad/sec.
