Title:
プロセス制御デバイスのフィードバック制御を切り替えるためのシステムおよび方法
Document Type and Number:
Japanese Patent JP2008509480
Kind Code:
A
Abstract:
Disclosed herein is a controller and method useful for transferring control of a process control device between first and second control modes. The controller includes first and second servo control modules that generate first and second drive signals based on feedback information from first and second sensors for control of the process control device in accordance with first and second control modes, respectively. The controller also includes a feedback control transfer module that transfers control of the operation of the process control device from the first control mode to the second control mode based on the feedback information from the first sensor. In certain embodiments, such control transfer involves a control routine that initially generates the second drive signal based on the first drive signal to effectuate a smooth, bumpless transfer between the control modes.
