It is a positive (phase) lead controller, which generates a complete control system T(s) stable, precise enough to step and with both enough speed, no oscillations and no overshoot

It is a positive (phase) lead controller, which generates a complete control system T(s) stable, precise enough to step and fast, but very oscillatory and with big overshoot

It is a positive PID (proportional integral and approximate derivative controller), which generates a complete control system T(s) stable, perfectly precise to step and with both enough speed and oscillations and overshoot small enough
