Summary
The PI controller has the following characteristics:
It sets the process value exactly to the command variable.
By so doing, it tends to oscillate and is unstable.
It requires more time to carry out the control action than the P controller .
PI controller
A PI controller reduces the loop error immediately and will eventually drive the loop error to zero.
: Manipulated variable at the time n
: Proportional part of the manipulated variable
: Integral part of the manipulated variable
: Manipulated variable of the I controller at the time n-1; also called integral
sum
: Gain of the P controller
: Gain of the I controller
: Sampling time, duration of a time slice
: Integral time; by means of this time the influence of the integral part is
controlled on the manipulated variable, also known as the integral-action time
