Gain reset rate

WebIn this method, the controller should be placed automatically with low gain and there shouldn’t be any reset or derivative. After that increase the gain slowly and when the oscillation starts make a slight change in the setpoint. Then the gain should be adjusted so that the oscillations can continue with a constant amplitude. http://www.gainrestoration.com/
