摘要： PURPOSE:To improve operability of a machine by providing a device for deciding a model deciding the compatibility of a model corrector that corrects nonconformity between a control quantity and a model control quantity and a corrector for the controller with the machine operated by an operator. CONSTITUTION:Through controlling the control quantity of a controller 2 by an operation device 1 handled by an operator, a machine 3 is worked and a device for improving operability is connected to the controller 2. A model 5 is corrected by a correcting device 8 with the control quantity when the model 7 of the machine 3 is corrected by the model of the operator and a model 6 of the controller 2, and actual control quantity. Further, the controller 2 and the model 6 are corrected by a controller corrector 10. Thus, for instance, it is possible to quantitatively evaluate operability corresponding to the feature of the operator and the factor of contents of work, and correct the machine constant. It is also possible to automatically improve the operability during operation and cope with a change in the contents of the working.

摘要： PURPOSE:To attain the optimum setting of characteristics such as the easy handling of a machine which is operated manually, the result of the work, etc., by using a means which integrates the deviation between the work load and the target value of the machine, a function conversion means and an arithmetic means. CONSTITUTION:The target value 1 of a machine produces a deviation epsilon with a controlled variable 6 at an adding point 2. Then an operator 3 operates a machine 5 to be a controlled system to decrease the deviation epsilon. Here an integrator 8 integrates the square of the deviation epsilon and delivers the result J of the work. The result J is supplied to a function converter 9 and the converter 9 converts the result (J) into a parameter function of the machine 5 and delivers it to a computing element 10. The computing element 10 obtains the parameters of the optimum gain, the time constant, the waste time, etc. of the machine 5. Based on these parameters, the parameter of the machine 5 is set or the machine 5 is designed. Thus it is possible to set the characteristics like the easy handing of the machine 5, the result of the work, etc. at the optimum levels respectively.

摘要： PURPOSE:To control operability by manually or automatically controlling an inserted compensator that changes constants of the system operation corresponding to the evaluation of an operator, contents of working, the characteristics of an operator and the results of the work, etc. in such a building machine as a shovel or the like. CONSTITUTION:An output machine 4 is drived through a driver 3 in accordance with the specification of a controller 2 by such an operating device as a lever or the like. In order to compensate the characteristics of the machines 1-4, compensators 1a-4a are inserted. The compensators 1a-4a are provided with constants inluencing the operability intended to improve such as operability, controllability or the like in addition to its original system of operation, and these constants are controlled by controllers 1b-4b. By manually controlling the controllers 1b-4b corresponding to the evaluation of an operator, the contents of working, characteristics of operator and the result of the work, the operability can be obtained as desired without attaching the evaluation or judgement of the operator also during operation.

摘要： PURPOSE:To locate highly accurately a movable body by memorizing the distance between a reference position detecting mechanism and each stop position and replacing the displacement of the movable body for the previously memorized displacement to correct accumulated errors. CONSTITUTION:A stacker crane 1 is provided with photo-electric switches 11a, 11b as detectors for detecting a reference position detecting mechanism 10, and driven by the power of a drive unit 17 through a drive mechanism 18 and braked by a braking mechanism 20. Also, a relay circuit 19 sends the input shut- off signal output to the drive unit 17 and is controlled such that the deflection of the actal speed of the crane obtained through a tachogenerator 13 from a desired speed of a speed pattern generator 16 is corrected through a comparator 21. A computer 14 sends the speed commanding signal output to a speed pattern generator 16 so as to reduce the deflection of the displacement of the crane shown by a counter 15 from desired address A and a counter 15, while generating the signal R to compensate for accumulated errors on the basis of the signal from a photoelectric switch 11.

摘要： PURPOSE:To make highly accurate positioning simply by finding a linear weighted average value of the result of control from measured value of positioning, and outputting the difference between the target command and the weighted average value as the next correction. CONSTITUTION:The learning correction of the result of positioning fn is given by Fn=(1-alpha).Fn-1+alphafn by a microcomputer 4, where Fn is linear weighted average value of the result of positioning and alpha is smoothing coefficient. Here, target command of control basing on the result of learning SS1 and correction DS1 for target of positioning SS are expressed by expressions I, II. Here, k is correction coefficient. Fn can be found by finding simple average stop position x, obtaining provisional correction DS1 from DS1=SS-x and supposing and giving alpha. Therefrom, k is obtained by the expression II. The difference between the target command SS1 and weighted average value Fn is outputted from a positioning device 2 as next correction.

摘要： PURPOSE:To evaluate the operability of a machine objectively and to obtain the relation between constants controlling the operation performance of the machine and the operability clearly, by operating a machine model by the operation by an operator and operating the machine model through an operator model. CONSTITUTION:A machine model 1 is operated by the operation by an operator to obtain the relation of the control result and the evaluating point of the operator to constants controlling the characteristics of the model 1. Then, the machine model 1 is operated by an operator model 13 to obtain the constants of the model 13 to express the control result obtained through the operation in the relation with the constants of the model 1. Thus, the operativity of machines which had been regarded that the evalution is impossible, can be evaluated objectively, and the relation between the constants controlling the operation performance of a machine and the operativity can be obtained clearly.
