how the addition of integral control improves the signal?

Proportional only control (P) normally gives a system that has a steady-state error, which means that the the process output is never exactly equal to the set point.
Adding Integral accion (I) to a Proportional only control (a PI control) allow you eliminate this steady-state error.
Increasing the integral time make your control system slower to eliminate the steady-state error, on the other hand, if you make your integral time to small your system could become unstable.

Adding a bit of integration control allows to control the process to a set average over time so the highs and lows are balanced out more than with a simple P control.

Well in my opion the PI control can only decrease the intergral action time
