摘要：AbstractThis paper considers the problem of global stabilization for a class of high-order nonlinear systems whose states cannot be measured accurately and the uncertain parameters occur in the powers of the measurement functions. Based on the notion of homogeneity with monotone degrees (HWMD), the conditions on the uncertain measurement powers that are related to the system powers will be given so that the homogeneous weights and degrees can be determined to guarantee the solvability of this problem. By adopting the adding a power integrator technique, a measurement feedback controller is proposed to globally stabilize the nonlinear system under different sensors with certain conditions.
