Title: Vector controller for induction motor
Inventor: YAMADA TETSUO
IPC: H02P21/22
Filed: 1989-07-12
Abstract: PURPOSE:To improve the accuracy of torque control by a method wherein secondary flux is estimated to correct a secondary time constant in the operating formula of a slip angle speed based on the value of estimation while the estimating operation of the secondary flux is effected so as to approximate an integrating element to a primary delay element. CONSTITUTION:The amount of change of a secondary resistance is obtained based on estimated secondary fluxes lambda2alpha, lambda2beta to operate the angular velocity omegas of slip considering the amount of change while either one of alpha-axis component or beta-axis component, for example, of the secondary flux is selected to employ it in accordance with the values of an exciting current (i1alpha) and a torque current (i1beta) upon obtaining the amount of change of the secondary resistance. The estimation of the secondary fluxes lambda2alpha, lambda2beta is obtained from the estimated value of a primary flux, however, the effect of offset is reduced, detection in a low frequency area is facilitated and an error is reduced since an integrating element is approximated to a primary delay element upon estimating the primary flux. Accordingly, the secondary resistance may be compensated across a wide frequency area.

Title: Method for controlling interface
Inventor: TSUNODA HARUHIKO
IPC: G06F11/00
Filed: 1984-08-30
Abstract: PURPOSE:To prevent a signal not intended by a program from being transmitted to a bus by adding ON of a flag of an interface part to the signal transmissible condition to a bus and turning, further a flag into ON by micro program recog nizing the drive demand. CONSTITUTION:At the time when a hardware recognizes a drive demand, i.e. the output of gates 4, 6 is 1, a gate 9 is opened to give a drive demand to a micro program mu. At this time, a driver DV does not turn ON because a gate 7 does not open, and nothing is transmitted to a bus 8. A driver DV turns ON after a flag 10 is set. At this state, mu acts receiving the drive demand, and a response signal to be transmitted to the bus 8 is set. Consequently, the correct response signal can be transmitted to the bus 8. When a logic device receives data and falls down the drive signal, the output of an OR gate 6 becomes at an L level, the drive DV turns OFF after gates 7, 9 are closed, the response signal and flag 10 are reset after the bus 8 is opened.
