Abstract
The present control apparatus and method for controlling a plurality of intercoupled industrial process operations each having an operation control member. The control member position correction is implemented in accordance with a predetermined characteristic so as to minimize undesired interference with the other industrial process operations.
Claims8
In a control apparatus for a plurality of independent industrial processes, with each said process including a process control member determining the operation of that process and providing a common operationally dependent intercoupling between said processes, the combination of:
- means coupled with each of said processes for independently establishing the operation of the process control member determining the operation of that process,
- means responsive to all of the established operations of the respective process control means for providing decoupled operational changes for the respective process control members, and
- means provided for each process control member and responsive to the decoupled operational change for that process control member determining the operation of the process control member for controlling the industrial process associated with that process control member.
In a method for controlling a plurality of independent industrial processes with each said process including a process control member determining the operation of that process and providing a common operationally dependent intercoupling between said processes, the steps of
- establishing the respective operations of all of the process control members,
- providing decoupled operational changes for each process control member in response to said established operations of the process control members, and
- determining the operation of each process control member in response to the decoupled operational change for that process control member.
