How is lead compensator calculated?
A lead compensator in frequency response form is given by the following. with p =1 / T, z = 1 / aT, and Kc = a. In frequency response design, the phase-lead compensator adds positive phase to the system over the frequency range 1 / aT to 1 / T.
What are the important steps in the design of a lag compensator?
The procedure that can be adopted to design with a cascade phase-lag compensator is: 1. Determine the frequency where the required phase margin would be obtained if the gain plot crossed the 0 dB line at this frequency. Allow for 5° phase lag from the phase-lag compensator when determining the new crossover frequency.
