Pick a phase margin preset and slide loop bandwidth. Behind the scenes the tool solves for compensator gain \(K\) and pole/zero locations in a plant-plus-Type-II compensator model, then shows the loop-gain Bode plot and a zoomed unit load-step response.
Plant with one pole, Type-II compensator (origin pole + zero/pole pair). PM presets fix the shape; bandwidth moves the crossover. Step size = 1. Green ○ = zero, red × = pole (origin pole at left edge).
