Abstract

In this paper, we propose an adaptive output feedback control law for MIMO nonlinear systems with distinct unknown measurement errors in each output. The nonlinear terms have incremental rates which include nonlinear functions of output and polynomials of output multiplying unknown constants. By introducing an observer, and two classes of particular dual adaptive high-gains and a class of exclusive constant high-gains, an output feedback controller is developed to stabilise the MIMO nonlinear system. The designed controller is able to tolerate uncertain measurement errors with a relatively wide range. Finally, some simulations are provided to corroborate the theoretical analysis.
