Air-powered motor has gradually been used in a variety of applications due to its superior characteristics such as low inertia, no electromagnetic interference, high power density, and no pollution. Therefore, the air-powered motor is competitive on the market. In this regard, the object of this project was to develop drive and control technologies for an air-powered motor control system as well as the development of a prototype of an air-powered vehicle and the evaluations of efficiency and endurance. Hence, this project completed the achievements including: (1) development of an air motor experimental platform; (2) characteristics analysis and measurements of the air motor; (3) modeling and simulation of the complete air-powered vehicle; (4) system identification and verification of the air motor; (5) innovative evolutionary two degree-of-freedom (DOF) proportional-integral-differential (PID) speed controller design, tuned by bacterial foraging algorithm; (6) practical experimental test on ECE-40 driving cycle. From the experimental and simulation results, it can be seen that the developed two-DOF PID controller can perform accurate speed control performances under unstable pressure, temperature and flow conditions. It indicates the feasibility of the air-powered vehicle in practical applications.
