Reduced-order Observer Design for One-sided Lipschitz Nonlinear Systems with Unknown Inputs

摘要：

　　This paper considers the reduced-order observer design problem for one-sided Lipschitz nonlinear systems with unknown inputs.The systems under consideration are a larger class of nonlinear systems than the well-studied Lipschitz systems and have inherent advantages with respect to conservativeness.For such systems,we propose a reduced-order unknown input observer (UIO) by using the linear matrix inequality (LMI) technique.Sufficient conditions that guarantee the existence of the reduced-order UIO are established and transformed into the format of LMIs via using the matrix generalized inverse technique.Simulation results are finally given to illustrate the effectiveness of the proposed design.
