Thursday, September 4, 2014: 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.
Friday, May 23, 2014: 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.
