• PID VIs: Use the PID VIs to implement PID control applications. The first three VIs on the PID palette are different versions of the PID VI. application. The other VIs on the PID palette can be used with one of the PID VIs for additional functionality.
• Fuzz Lo ic
Is: Use the Fuzz
Lo ic VIs to im lement fuzz controllers designed with the Fuzzy Logic Controller Design Project Manager. Use the Load Fuzzy Controller VI and the Fuzzy Controller VI . Fuzzy Control VI as an example to test the input/output behavior of your fuzzy controller.

PID Advanced VIs ALSE.. manual manual contr control ol s ecifies the value of the control out ut when auto? is FALSE auto? specifies whether to use automatic or manual control. When auto? is , . , manual control. This VI uses bumpless transfer from manual control to automatic control. The default is TRUE. output range specifies the range to which to coerce the control output. The default range is –100 to 100. output high specifies the maximum value of the controller output. The default is 100. output low specifies the minimum value of the controller output. The default is –100.

setpoint /process /process variable range. This VI uses the setpoint range to calculate non-linear integral action. The default range is 0 to 100. /process setpoint low specifies the minimum value of the setpoint /process variable range. /process setpoint high specifies the maximum value of the setpoint /process variable range.
PID gains specifies the proportional gain, integral time, and derivative proportional gain (Kc) specifies the proportional gain of the controller. The defaul defaultt is 1. In the e uation uation that that define definess the PID control controller, ler, KC represents the proportional gain. integral time (Ti, min) specifies the integral time in minutes. The default is 0.01. derivative time (Td, min) specifies the derivative time in minutes. The e au s .

PID Advanced VIs reinitialize? specifies whether to reinitialize the internal parameters, such as the inte inte rated rated erro errorr of the contro controlle ller. r. The The defa default ult is is FALS FALSE. E. beta specifies the relative emphasis of disturbance rejection to setpoint tracking. The default value of 1 is appropriate for most applications. ou can use a sma er va ue etween an to spec y emp as s on disturbance rejection, such as process load changes.
. linearity is 0 to 1. A value of 1 provides a normal linear response, while a value of 0.1 provides an approximately parabolic response. output returns the control output of the PID algorithm that is applied to the controlled process. t out s returns t e actua t me nterva n secon s. t out s returns either the value of dt (s) or the computed interval if you set dt (s) to –1.
