Abstract: The smoothness of acceleration and deceleration process is
a serious problem in valve control system with high inertia loads. The
meter-in and meter-out independent regulating valve control unit is
applied. Based on this unit, a grading control algorithm in dynamic
process of high inertia loads is put forward. After the velocity
approaches its command, a state feedback control algorithm based on
parameters on line estimating is employed to guarantee both its velocity
accuracy and the smoothness of dynamic process. Experiments show that
the actuator’s velocity could increase or decrease to its command
accurately, smoothly and rapidly after the above unit and algorithms are
applied.
Key words: High inertia loads Acceleration and deceleration performance
