Make sure the sampling period is 1ms, based on experience to determine optimal step 4, step 6 forecast. Model length error correction vector is taken as 20 days is taken as {1,07, o3, 0.02, a 0.3, a 01}. Simulation results show that these parameters can guarantee the stability of the real system.

The power control algorithm for improving the tracking accuracy of servo systems,<a href="http://www.uggs-onlinebestellen.org" target="_blank" class="postlink">uggs online bestellen</a>, to improve the quality of the system has a good effect.
