Hello,
I'm tryng the pid_controller (both, oscat and util library) and I can't get it works. I'would like to handle the temperature of heaters by SSR and bang bang control. The "analog" pid value will be converted by a PWM_DC module
I've tried to change the KP and TN parameters in different ways, but it always try (the block) to reach the set point increasing the output value Y up to the maximum (LH) . Once the ACTUAL value is >= the SET point, it starts to decrease the value at the speed of KP and TN variables
Is it possible that there is no way to reduce the output value when the actual value is around the setpoint?
