Design of Forecasting Embedded System Based on Time Series
Guorui Zhu · 2014
Forecasting embedded system uses ARM( LPC213) and FPGA( CycloneII) to get the displacement of rotary table. The model AR of time series by the displacement is built to forecast increasmental displacement and output the increasmental displacement by PWM. Time grating sensor can work as displacement sensor of digital control system by forecasting embedded system transferring the signal of time grating sensor. The Experiments show that the precision of forecasting embedded system can reach ± 1 angle of second. Forecasting embedded system can solve the problem of incompatible.
