Adaptive stabilization of a class of high‐order uncertain nonholonomic systems with unknown control coefficients

摘要: SUMMARY This paper is concerned with the globally stabilizing control design for a class of high-order nonholonomic systems. Compared existing literature, systems under investigations have more uncertainties and unknowns, such as neither lower nor upper bound known each coefficient This renders methods highly difficult to problems or even inapplicable. In this paper, by defining two new unknown parameters whose dynamic updating laws are properly chosen also using discontinuous coordinates transformation method adding power integrator, approach given adaptive controllers A numerical simulation provided demonstrate effectiveness theoretical results.
