Feedback Control Systems: Design with Regard to Sensitivity

A compensation design method is proposed, which not only secures a desired location for the dominant roots on the s plane, but also satisfies conditions concerning the sensitivity of these dominant roots to the varying plant parameters. Examples are solved and verified on the analog computer.
