A 2

sided controller can output a manipulated variable in the range from -100 % to +100 %, i. e. the
manipulated variable is bipolar. The manipulated variable is positive if the controller should increase the
process value. In the case of a pure P-controller, this means that the value of the controlled variable x is smaller
than the set point w. On the other hand, the manipulated variable is negative if the process value should be
decreased. The value for x is greater than the set point w.
