摘要： A multivariable control system for controlling boiler burners. The system includes burner actuators, boiler sensors, a control system coupled to the actuators and the sensors and further includes a memory and a processor, and an application stored in the memory. When executed by the processor, the application executes a multivariable control algorithm to determine actuator manipulated variable values to control in part the burners based on data received from the sensors and based on a plurality of gain values. The application also executes an adaptation algorithm to change an actuator manipulated variable value, to maintain the changed manipulated variable value for a pre-determined period of time, to determine a change in data received from the sensors, to determine a gain value based on the changed manipulated variable value and the change in data received from the sensors, and to provide the determined gain value to the multivariable control algorithm.

摘要： A control and measurement system for a coriolis flowmeter having a flowtube, a driver adapted to vibrate the flowtube, and a pair of sensors adapted to generate signals indicative of movement of the flowtube when it is being vibrated by the driver, wherein the sensors are positioned relative to one another so the signals from the sensors are indicative of a mass flow rate of fluid through the flowtube. A digital drive signal generator is adapted to generate a variable digital drive signal for controlling operation of the driver. The digital drive signal generator can be adapted to cause the driver to resist motion of the flowtube during a first time period and amplify motion of the flowtube during a second time period. The digital drive signal generator can also be adapted to initiate motion of the flowtube by sending one or more square wave signals to the driver.

摘要： Methods and systems for preserving the life of a power source of a wireless end node of a wireless communication system for use in a mobile environment are provided. In one embodiment, a method is provided that includes wirelessly transmitting a wireless end node acknowledgment message to a network coordinator during a normal operation mode of the wireless end node. The method also includes the wireless end node monitoring for a network coordinator acknowledgment message from a network coordinator in response to the wireless end node acknowledgement message during the normal operation mode of the wireless end node. Also, the method includes incrementing a missed acknowledgment counter value stored in a memory storage of the wireless end node when the network coordinator acknowledgment message is not received. Further, the method includes increasing a time period of a sleep timer of the wireless end node when the missed acknowledgment counter value equals a missed acknowledgment threshold.

摘要： A flowmeter is disclosed. The flowmeter includes a vibratable conduit, and a driver connected to the conduit that is operable to impart motion to the conduit. A sensor is connected to the conduit and is operable to sense the motion of the conduit and generate a sensor signal. A controller is connected to receive the sensor signal. The controller is operable to detect a single-phase flow condition and process the sensor signal using a first process during the single-phase flow condition to generate a validated mass-flow measurement. The controller is also operable to detect a two-phase flow condition and process the sensor signal using a second process during the two-phase flow condition to generate the validated mass-flow measurement.
