Control of the motion of nonholonomic systems
… and stabilisation of nonlinear, non¬holonomic systems. It is shown that the kinematics of the system can be separated from the dynamics of the system by using successively two inverse dynamics type of transformations. This leads to a linear decoupled kinematical system, control strategies can …

Dynamics and Control of Higher-order Nonholonomic Systems
… is established for the control of higher-order nonholonomic systems, defined as systems that satisfy higher-order nonintegrable constraints. A model for such systems is developed in terms of differential-algebraic equations defined on a higher-order tangent bundle. A number of control-theoretic …

Feedback Control and Nonlinear Controllability of Nonholonomic Systems
… we study the methods for motion planning for nonholonomic systems. These systems are characterized by nonholonomic constraints on their generalized velocities. The motion planning problem with constraints on the velocities is transformed into a control problem having fewer control inputs than …

Global Formulation and Control of a Class of Nonholonomic Systems
… thesis study motion of a class of non-holonomic systems using geometric mechanics, that provide us an efficient way to formulate and analyze the dynamics and their temporal evolution on the configuration manifold. The kinematics equations of the system, viewed as a rigid body, are constrained by …

Hybrid Switched System Visual Servo Control
Furthermore, nonholonomic systems present a control task that is not suitable for a single, continuous feedback controller. Switched-system control of IBVS and PBVS systems offer the opportunity to use vision data in the closed loop control of a nonholonomic system. We present such a …

Nonholonomic Feedback Control Among Moving Obstacles
… controller is developed for navigating a nonholonomic vehicle in an area with multiple stationary and possibly moving obstacles. Among other applications the developed algorithms can be used for automatic parking of a passenger car in a parking lot with complex configuration or a ground …

Nonlinear Control for Dual Quaternion Systems
… for a total of 6 DOF. Many complex mechanical systems exhibit this type of motion, with constraints, such as complex humanoid robotic systems, multiple ground vehicles, unmanned aerial vehicles (UAVs), multiple spacecraft vehicles, and even quantum mechanical systems. These motions historically …

Model Abstraction in Dynamical Systems: Application to Mobile Robot Control
… the reachability properties of nonlinear systems. Such consistent hierarchies of reachability-preserving nonlinear abstractions are considered for the robotic car. Not only can these abstractions be analyzed with respect to some behavior of interest, they can also be used to transfer …

Nonholonomic Control Utilizing Kinematic Constraints of Differential and Ackermann Steering Based Platforms
A nonholonomic tracking controller is designed and adapted to work with both differential steering and Ackermann steering based platforms whose dynamics are represented using a unicycle model. The goal of this work is to find a relatively simple approach that offers a practical alternative to bulky …
