Abstract: 1,199,996. Adaptive automatic control. INTERNATIONAL BUSINESS MACHINES CORP. Dec. 27, 1967 [Jan.16, 1967], No. 58606/67. Heading G3R. In a closed loop manufacturing process control system, one of a predetermined number of controller gain settings is automatically selected in dependence on a comparison between an error signal during one period and an error signal during a preceding period. In Fig.1, signals corresponding to the magnitudes of a number of variables of a process 10 are applied to an analogue or digital computer 22 which calculates therefrom set point signals for a number of controllable variables of the process. For each controlled variable, the set point signal is compared, in a comparator such as 16, with a signal corresponding to the setting of a controller 14 for that variable so that any difference is eliminated by adjustment of controller 14 through an error-actuated control system 18 provided with suitable phase-shift and bandwidth. The square of the error is integrated during successive time intervals by a sampling circuit 30 and applied to a memory 32 so that successive integrals are compared at 34. After each comparison, a variable gain device 24 for control system 18 is automatically adjusted by one step in a forward or reverse direction according to whether the error integral has decreased or increased. The adjustment of gain also reverses when it reaches a limit in either sense. The set point signals for the several controlled variables may operate through separate control loops as shown or they may be applied through a multiplex system.

Title: Improvements relating to touch-wire detection systems

Filed: 1969-12-12
Abstract: 1278338 Touch-operated switching arrangements PLESSEY CO Ltd 3 Dec 1970 [12 Dec 1969] 60684/69 Heading H3B [Also in Division G4] In a switching arrangement which senses bridging by human touch of a pair of electrically separated conductors, one conductor (TWS) b, Fig. 2, is connected at a virtual earth point VE to one input of a two-input operational amplifier OPA1, and the other conductor (TWS) a is connected to a negative potential ve-, the second input of the operational amplifier being connected to a referance bias source ER2 which raises the potential of point VE positively and hence the amplifier input level, the amplifier providing a discrete voltage change in the output path R7, R8 when the conductors are bridged. Amplification is effected by a second operational amplifier OPA2 associated with a logic level clamp circuit LLC1 providing logic level outputs at O/P1 and O/P2. In a modification, Fig. 6, an isolated guard wire GL is included between conductors a and b, and is connected to the reference bias source ER2, this wire preventing false operation of the switching arrangement due to leakage between conductors a and b. A switching arrangement utilizing a group of touch conductor pairs TW1 -TWE is shown in outline in Fig. 1, each conductor pair being connected to a respective operational amplifier sense circuit SC1-SCN and clamp circuit LLC1-LLCN of the kind shown in Fig. 2. Compensation for drift, primarily due to temperature variation, is provided by a drift correction circuit DCC which regulates and supplies a potential EC, Fig. 2, from which the virtual earth potential VE is derived. The outputs from the clamp circuit are applied to a converter L/B CONV for conversion to binary code form, and pass both to a set of data staticizers STATS receiving a code on leads A-E indicative of the conductor pair touched, and to control logic CL, the latter circuit being described in detail in Fig. 5 (not shown). The control logic rejects touch operations of less than a given duration, while touch in excess of this period sets a data ready bistable DRT when the touch terminates. Resetting of DRT is effected from the data output over lead RR. An output control signal on lead OPC supplied in response to the data ready signal causes the state of toggles in O/PRG to be applied to leads DBA-DBE. In the event of more than one conductor pair being touched simultaneously, setting of the data ready bistable DRT is inhibited by an analogue fault detector FD which transmits a signal over a clamp circuit LLCF and a fault bi-stable FT, this bi-stable being reset when the next touch signal is detected by the control logic CL. The fault detector FD and associated clamp circuit LLCF are described in detail in Fig. 4 (not shown).
