Phase lag compensator matlab torrent

Similarly, the phase margin is the difference between the phase of the response and 180 when the loop gain is 1. The instantaneous gain of the compensator is 1, and the dc gain is equal to 1z1p, where z is the zero and p is the pole of the compensator the block implements a lead compensator when 0 phase lag compensator also can be designed using a frequency response approach. In other words, the gain margin is 1g if g is the gain at the 180 phase frequency. Interactive educational tool for the design of compensators using.
