A “PID” algorithm is typically used by a BAS to implement closed loop control. In short, a PID algorithm (which is part of the “Controller” programming) compares the “Sensed Variable” to the setpoint, ...

The days when converter manufacturers would have little option but to rely on the expertise of power-module specialists to design filters, optimize the control loop ... can now be achieved in a simple ...

If the condition is never met, then the program loops infinitely. Consider this simple algorithm to count up in twos from one to a hundred: the variable ‘count’ is set to 1 the ‘while ...
