This study introduces a method to establish the dynamic model of a parallel robot using screw theory and the d’Alembert-Lagrange equation. Based on this model, a robust sliding mode control strategy utilizing hyperbolic convergence laws is proposed. The d’Alembert-Lagrange equation and screw theory are employed to construct a concise dynamic equation ...
