This study proposes a novel parallel dual inverted pendulum system (PDIPS), which consists of a pair of parallel linear servomotors with each carrying an inverted pendulum (IF). The potential applications of the PDIPS include transportation, power-aided tools and rehabilitation. For the two inverted pendulums to move in synchronization, the control problem combines the classical IP control issue and the synchronous tracking control of the two linear motors. Hence, this study aims to develop a control scheme to achieve the balancing of both individual IPs and their synchronization for the PDIPS. Simulation and experimental results show the feasibility of the proposed control scheme for the PDIPS.
