Compensator design for non-minimum phase systems

Click For Summary
SUMMARY

The discussion focuses on designing compensators for open loop non-minimum phase transfer functions. It highlights the use of complementary root locus techniques as a standard practice for achieving desired closed loop pole locations, particularly when a negative gain is involved. Participants emphasize the importance of understanding the implications of non-minimum phase behavior on system stability and performance. The conversation underscores the necessity of selecting appropriate design methodologies to ensure effective compensator performance.

Hi

Given an open loop non-minimum phase transfer function, what in general are the approaches preferable to design a compensator for it? Suppose one is given the location of the desired closed loop poles, is it a standard practice to use complementary root locus (or negative root locus) for design, assuming a negative value of the gain?

Thanks.
