英文摘要: This project studies the problem of nonholonomic control systems with rheonomous affine kinematic model constraints. For the kinematic system with rheonomous affine constraints, it will be further converted by constructing the nonlinear transformation. On this basis we will discuss its controllability, explore the possibilities of realizing the nonholonomic chained system with the similar nonlinear drifts, and further design the stabilization and tracking controller. When the kinematic system has the affine or rheonomous affine constraints and the dynamic system possesses the uncertainties, by using the finite time control method we will design the finite time convergence tracking controller to achieve the tracking control of the kinematic system. When the kinematic system can be tranformed into the nonholonomic chained system with nonlinear uncertainties and the dynamic system possesses the uncertainties, via a nonlinear construction, we will apply the input-to-state stable(ISS) method to design the stabilization and tracking controller. We will investigate the nonholonomic system whose kinematic constraint is partially integrable, by using the differential-algebraic control system theory, to achieve the stabilization and tracking control objective via state and output feedback. Combining the nonholonomic chai
