Abstract: The "Made in China 2025" initiative will require full automation in all sectors, from customers to production. This will result in great challenges to manufacturing systems in all sectors. In the future of manufacturing, all devices and systems should have sensing and basic intelligence capabilities for control and adaptation. In this talk, multiscale dynamics of the modern manufacturing system will be discussed and the multi-phase integrated design methodology will be proposed. For a real-world application, sensing and modeling are always the essential steps towards the advanced control and operation. A smart sensing based integrated modeling will be presented for the jet dispensing process – a multi-time scale dynamic system in IC packaging industry. Finally, another intelligent method will be presented for effectively modelling of the space-time coupled dynamic systems, and applied to the thermal process widely existing in the industry.

Abstract: Magnetostrictive actuators featuring high energy densities, large strokes and fast responses are playing an increasingly important role in micro/nano-positioning applications. However, such actuators with different input frequencies and mechanical loads exhibit complex dynamics and hysteretic behaviors, posing a great challenge on applications of the actuators. To this end, a comprehensive model is developed. According to the proposed hysteresis model, an inverse Asymmetric Shifted Prandtl-Ishlinskii (ASPI) Model is proposed for the purpose of compensating the hysteresis effect. However, in real systems, there always exists a modeling error between the hysteresis model and the true hysteresis. The use of an estimated hysteresis model in deriving the inverse compensator would yield some degree of hysteresis compensation error. To accommodate such a compensation error, an analytical expression of the inverse compensation error is derived first. Then, a prescribed adaptive control method is developed to suppress the compensation error and simultaneously guaranteeing global stability of the closed loop system with a prescribed transient and steady-state performance of the tracking error. The effectiveness of the proposed control scheme is validated on the magnetostrictive- actuated experimental platform.

Abstract: Ridesharing of bicycles and electric scooters has surged in major cities all over the world, benefiting many commuters by improving efficiency, reducing congestion in road and reducing parking space. One of the main problems of the ridesharing is when riders have arrived at their destinations, they park their vehicles in their most convenient spots, often blocking traffic of the others. Riding bikes and scooters also requires substantial training time in order to be safe. With the rapid progress in robotic dynamics, control and computer vision, an intelligent self-balance, self-driving scooter can solve many problems facing ridesharing today. First, with sophisticated nonlinear dynamics, bicycle and scooter can be modelled accurately, allowing complex control scheme to be deployed for self-balancing, thus greatly improving safety. Second, using only low-cost sensors, such as ultrasonic and video camera, one can realize low speed self-driving when no rider is using the vehicle. This capability will deliver the vehicle to the needed rider from its designated park space autonomously and return to its charging station autonomously when rider has arrived at his destiny. This abstract will review the recent progress in scooter modeling and control, computer vision for navigation and obstacle avoidance as well as our currently prototype for the perfect ridesharing vehicle.
