| Abstract: | The constraint equations expressed by state variables were introduced, and new variational principles of kinematic constrained systems in state space were established. The equations of motion with multiplier and in general state variables for kinematic constrained systems were derived. It is shown that the motion equations of constrained systems in state space are singular. An example was given to illustrate the application of the result. |
