There are challenges and opportunities in supporting the infrastructure for electric vehicle (EV) and smart grid in a dense urban city-state like Singapore. Automotive telematics which typically use cellular networks, can potentially be served by picocells of 5.9 GHz Dedicated Short Range Radio(DSRC) network for intelligent transport system(ITS), connected to our national fiber network (NG-NBN), which...
With the aim to improve the servo performance of hard disk drives, this paper proposed a multi-sensing and multi-rate controller to compensate the head actuator assembly vibration. To perfectly measure the most important resonance modes of the voice coil motor (VCM) and suspension, a cheap but effective PZT sensor is attached to the arm of the actuator. A robust controller is developed with the μ-synthesis...
