The control system error can be calculated as the difference between the values of the set point and the measured variable. True O False Control systems are used to maintain process conditions at their desired values by manipulating certain process variables to adjust the variables of interest. False True The time constant of the system can be defined as the time required for response to reach 94% of its ultimate value. False O True
