A method for designing nonlinear fixed‐order (i.e. full‐ and reduced‐order) dynamic passive controllers for passive systems is developed using nonlinear dissipation theory. Specifically, by extending linear passive controller synthesis frameworks a family of globally asymptotically stabilizing nonlinear passive controllers is developed that can serve to enhance system performance and energy dissipation. The proposed approach is applied to the rotational/translational proof‐mass actuator (RTAC) nonlinear benchmark problem to develop fixed‐order dynamic output feedback nonlinear controllers. © 1998 John Wiley & Sons, Ltd.
