This is a textbook and reference for readers interested in
quasilinear control (QLC). QLC is a set of methods for performance
analysis and design of linear plant or nonlinear instrumentation
(LPNI) systems. The approach of QLC is based on the method of
stochastic linearization, which reduces the nonlinearities of
actuators and sensors to quasilinear gains. Unlike the usual -
Jacobian linearization - stochastic linearization is global. Using
this approximation, QLC extends most of the linear control theory
techniques to LPNI systems. A bisection algorithm for solving these
equations is provided. In addition, QLC includes new problems,
specific for the LPNI scenario. Examples include Instrumented
LQR/LQG, in which the controller is designed simultaneously with
the actuator and sensor, and partial and complete performance
recovery, in which the degradation of linear performance is either
contained by selecting the right instrumentation or completely
eliminated by the controller boosting.
