Filed: 1988-05-12
Abstract: PURPOSE: To lower costs by forming one shaft of multi-shaft planetary gear apparatus as an input shaft, to which an adjustable displacement type machine is connected through a plurality of gears, and connecting a constant volume displacement type machine with the second shaft of the multi-shaft planetary gearing apparatus. CONSTITUTION: A high speed coupling shaft A and a low speed coupling shaft E can be alternatively connected with at least two of auxiliary transmission stages or gears through gear clutch Z1 to Z4 used for gear changing. All of the auxiliary transmission stagesact on the output shaft of the transmission apparatus. The coupling shafts A, E are also changed accompanied with the changing of the gears. In extreme position of the hydrostatic transmission at which the coupling shaft A, E has the same speed, the multi-shaft planetary gear apparatus, is circulated as clutches. Therefore at this position, the gear to be changed must show the same transmission ratio. Because two gears are realized by one auxiliary transmission stages alternatively connecting with a high speed coupling A or a low speed couplings E, the gearbox is not too large in size and its members are reduced.

Filed: 1984-06-06
Abstract: PURPOSE:To secure the smooth nonlinear compensation with no discontinuousness by giving interpolation to the nonlinear compensation amount obtained between sampling time points by means of the nonlinear compensation carried out at sampling time points before and after said compensation amount. CONSTITUTION:A manipulator 1, i.e., a control subject compares a target amount with a feedback amount through a feedback arithmetic circuit 2 in a prescribed control cycle and is controlled by the control output (torque command) tauL that sets the deviation of said comparison at zero. Here a sampling circuit 3 is added together with an estimating circuit 4, an arithmetic circuit 5 for nonlinear compensation amount, a backup circuit 6 and a loop which obtains the nonlinear compensation amount tauNL of an interpolation circuit 7. Then the command tauL is compensated with the amount tauNL to obtain the control output tau. Based on the amount tauNL, both the position and the speed at the sampling time point following the next time point are estimated by the circuit 4 with the function approximation based on the present and past time series data. The circuit 5 calculates the compensation amount gammaNL according to said estimated position and speed. Then the nonlinear compensation amount of the corresponding time point is obtained by the circuit 7.
