In a process where fluid flow is in the range of 250 -300 units a PID controller is installed to monitor and control the fluid flow. The following data for of a P, I, D feedback are provided to a PID controller Proportional constant: 0.87 Integral constant: 0.37 Derivative constant: 1.45 Current error = 12.7 Average change in error ( Integral input) : 0.43 Rate of Change in error (Derivative Input) : 0.14 Calculate the total correction u that is to be provided by the controller using the principles of PID control
