●
PID proportion Gain:
Let the output of inverter and error signal proportional relations, only
the system output have steady state error coefficient when proportional control. The larger the
proportion when movement,the faster of speed and the sensitiver of action with system.When the
proportion is too larger, number of shocks increased,adjust time will long,and the system became
instability.
●
PID integration Gain:
Let the output of inverter and integration of error signal proportional
relations.In order to eliminate steady state error coefficient, need integrational control.The larger
the integration, the integral action will too less to eliminate the steady state error coefficient, The
smaller it will hard to eliminate the steady state error coefficient, when the integration is too less,
the system became instability.
●
PID differential Gain:
Let the output of inverter and differential of error signal proportional
relations. The differential control can not used solely, it userd with proportion gain and integration
gain to constitute PID control. The differential control can improve the movement performance for
the controlled plant witch has larger inertia or delaide.
