Abstract
Abstract A self-organizing control system having a plurality of selforganizing controllers acting in parallel to provide actuation signals for plant control. The controllers are constantly monitored to locate faulty controllers. When one controller does not compare with the others, it is initially coerced to operate correctly and, after a predetermined period, if correct operation is not provided, the faulty controller is removed from the system. In one embodiment, an odd number of controllers is always in the system to provide control on a majority basis. Therefore, the removal of a faulty controller will require the removal of an operating controller as well.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
57 words
A self-checking control system which comprises an odd plurality of control devices, said control devices acting in parallel with each other to provide a control output, and means responsive to a fault in one of said control devices for removing said one of said control devices and an additional one of said control devices from said system.
Claim 2
Dependent Claim
57 words
A self-checking control system which comprises an odd plurality of control devices, said control devices acting in parallel with each other to provide a control output, and means responsive to a fault in one of said control devices for removing said one of said control devices and an additional one of said control devices from said system.
Claim 3
Dependent Claim
39 words
A self-checking control system as set forth in claim 1 further including means responsive to a second faulty device for removing said second faulty device from said system and replacing said additional one of said devices into said system.
Claim 4
Dependent Claim
45 words
A self-checking control system as set forth in claim 1 further including means responsive to removal of said devices from said system for increasing the output of the remaining ones of said odd plurality of control devices to retain the level of said control output.
Claim 5
Dependent Claim
45 words
A self-checking control system as set forth in claim 2 further including means responsive to removal of said devices from said system for increasing the output of the remaining ones of said odd plurality of control devices to retain the level of said control output.
Claim 6
Dependent Claim
43 words
A self-checking control system as set forth in claim 1 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down said system.
Claim 7
Dependent Claim
43 words
A self-checking control system as set forth in claim 2 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down said system.
Claim 8
Dependent Claim
42 words
A self-checking control system as set forth in claim 3 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down system.
Claim 9
Dependent Claim
43 words
A self-checking control system as set forth in claim 4 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down said system.
Claim 10
Dependent Claim
71 words
A self-checking control system which comprises a plurality of control devices acting in parallel to provide a single control signal, means responsive to the faulty operation of any one of said control devices to coerce said one of said control devices into proper operation and means responsive to a predetermined time length of faulty operation of said one of said control devices for shutting down said one of said control devices.
Claim 11
Dependent Claim
71 words
A self-checking control system which comprises a plurality of control devices acting in parallel to provide a single control signal, means responsive to the faulty operation of any one of said control devices to coerce said one of said control devices into proper operation and means responsive to a predetermined time length of faulty operation of said one of said control devices for shutting down said one of said control devices.
Claim 12
Dependent Claim
22 words
A self-checking control system as set forth in claim 9 wherein an odd plurality of said devices is present in said system.
Claim 13
Dependent Claim
40 words
A self-checking control system as set forth in claim 10 wherein said means responsive to faulty operation in one of said control devices for shutting down said device also removes an additional one of said control devices from said system.
Claim 14
Dependent Claim
39 words
A self-checking control system as set forth in claim 11 further including means responsive to a second faulty device for removing said second faulty device from said system and replacing said additional one of said devices into said system.
Claim 15
Dependent Claim
38 words
A self-checking control system as set forth in claim 11 further including means responsive to removal of said devices from said system for increasing the output of the remaining devices to retain the level of said control signal.
Claim 16
Dependent Claim
44 words
A self-checking control system as set forth in claim 12 further including means responsive to removal of said devices from said system for increasing the output of the ones of said devices operating in said system to retain the level of said control signal.
Claim 17
Dependent Claim
43 words
A self-checking control system as set forth in claim 11 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down said system.
Claim 18
Dependent Claim
43 words
A self-checking control system as set forth in claim 12 further including means responsive to the existence of only two nonfaulty devices for retaining said system in operation and means responsive to a nonmatch of said two devices for shutting down said system.
