Tn this paper, a new FPGA-based motion control IC with embedded DSP core for high-speed gantry-type boring and milling machine tool is proposed to control the two decoupling linear motors. The FPGA-based IC has functions of trajectory generation, decoupling control, adaptive control, closed current loop control, current sensing module, encoder logic, PWM modulation, communication module and analog...
Participatory sensing has gained increasing attention in recent years as it is promising for empowering large-scale monitoring and knowledge discovery, leveraging a crowd of public smartphone workers. In a participatory sensing system, the platform recruits workers to participate in multiple sensing processes. However, sensing processes have limited budgets. A smartphone is only satisfied when it...
This paper proposes a new interval modulated target sensing scheme for energy restraint wireless sensor networks. While most of recent researches assume a time invariant sensing interval, our proposed sensing scheme considers the selection of sensing sensors and the modulation of sensing intervals at the same time. We utilize particle filter algorithm to get the predicted target state, which is used...
