Computing a stabilizing static output-feedback (SOF) controller is an NP-hard problem, in general. Yet, these controllers have amassed popularity in recent years because of their practical use in feedback control applications, such as fluid flow control and sensor/actuator selection. The inherent difficulty of synthesizing SOF controllers is rooted in solving a series of non-convex problems that make the solution computationally intractable. In this note, we show that SOF synthesis is a convex problem for the specific case of systems with a l o s s l e s s (ie, energy-conserving) nonlinearity. Our proposed method ensures asymptotic stability of an SOF controller by enforcing the l o s s l e s s behavior of the nonlinearity using a quadratic constraint approach. In particular, we formulate a bilinear matrix inequality (BMI) using the approach, then show that the resulting BMI can be recast as a linear matrix inequality (LMI). The resulting LMI is a convex problem whose feasible solution, if one exists, yields an asymptotically stabilizing SOF controller.
