Passivity Based Control Of Stewart Platform For Trajectory Tracking[Full-Text ]
Mr Tariku Sinshaw

Passivity based control, as one of the tools available to design robust controllers, is introduced for trajectory tracking of the Stewart platform. Since Passivity is a fundamental property of many physical systems which may be roughly defined in terms of energy dissipation and transformation, its inherent input output property quantifies and qualifies the energy balance of a system when simulated by external inputs to generate some outputs. PD+ controller is designed based on passivation principle so that the closed loop system becomes globally uniform and asymptotically stable.
