Abstract
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.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
126 words
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.
Claim 2
Dependent Claim
126 words
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.
Claim 3
Dependent Claim
25 words
The control apparatus of claim 1, with the decoupled operational change providing means determining the interaction of each process in relation to the other processes.
Claim 4
Dependent Claim
46 words
The control apparatus of claim 1, with the process control member operation establishing means providing an estimated process control member operational change for each said process, and with the decoupled operational change providing means being responsive to the estimated operational change of each process control member.
Claim 5
Dependent Claim
20 words
The control apparatus of claim 1, with the process control member operation determining means being responsive to a hysteresis offset.
Claim 6
Dependent Claim
22 words
The control apparatus of claim 1, with said decoupled operational changes being in relation to the positions of said process control members.
Claim 7
Dependent Claim
91 words
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.
Claim 8
Dependent Claim
91 words
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.
Claim 9
Dependent Claim
21 words
The method of claim 6, with the decoupled operational change including the hysteresis effect of the process control member position change.
Claim 10
Dependent Claim
19 words
The method of claim 6, with the decoupled operational change being responsive to the intercoupling between the industrial processes.
