Abstract :
In this note, we give a general result on the control of linear systems with measurement nonlinearities and multiple inputs and multiple outputs. We prove that if the measurement nonlinearities satisfy a sector condition and the system has vector relative degree and its invariant zeroes have nonpositive real part then there exists a linear measurement feedback controller which semiglobally stabilizes the system.
