This paper presents a complete set of methods for the performance analysis and design of closed loop systems with nonlinear actuators and sensors (so-called Linear Plant/Nonlinear Instrumentation, or LPNI, systems). As it turns out, these methods are quite similar to those in the linear case. Accordingly, the resulting methods are referred to as Quasilinear Control (QLC) Theory. Since the main analysis and design techniques of QLC are not too different from the well known linear control-theoretic methods, QLC can be viewed as a simple addition to the standard toolbox of control engineering practitioners and students alike.
