Step 211, after detecting that difference e is stable, detection of end.
PID closed loop control algorithms are based on PID controller, and in PID controller, P is a kind of simplest
Control mode, during P output proportional to input error signal relation, only proportional control system output deposit
In steady-state error；In integration I control, the output of PID controller and being integrated into for input error signal
Proportional relation, in order to eliminate steady-state error, integral term is must be introduced into PID controller.Integral term is to by mistake
Difference depends on the integration of time, increases over time, integral term can increase.So, even if error very little,
Integral term can also be increased over time and increased, and integral term promotes the output increase of PID controller to make stable state
Error further reduces, until equal to zero.Therefore, the PI in PID controller can be such that system is entering surely
Without steady-state error after state.In differential controls D, the output of PID controller and the differential of input error signal
(i.e. the rate of change of error) is proportional, and differential term can predict the trend of error change, can make in advance
The control action for suppressing error is equal to zero, even negative value, so as to avoid the serious overshoot of controlled volume.
