Terry Blevins gave a paper presentation at the American Control Conference, Portland, OR on PID Control Using Wireless Measurements. |
| This paper shows how the same quality of control as wired PID can be provided by PIDPlus using a wireless measurement, despite slower wireless measurement update and communication interruptions. The paper presents and evaluates an alternate approach of PID control accounting for non-periodic measurements with a Kalman filter observer that has been modified for use with a wireless measurement. A second alternative shows how the Smith Predictor may be modified to work with a wireless measurement. Test results are presented that compare the PIDPlus performance to that achieved using these alternate approaches for a variety of operating conditions that may be encountered when using wireless transmitters. |

At a special press briefing in Beijing, the HART Communications Foundation announced that the HART Communication Protocol (including WirelessHART) has been approved as China National Standard, GB/T 29910.1 ~ 6-2013. China’s adoption of WirelessHART as a national standard is another indication of the world wide acceptance of WirelessHART within the process industry. |
