    摘要: A pulse generating device according to the present invention is operated in accordance with a pulse control command including output time data about output pulse given from external equipment such as a CPU. The pulse control command including the output time data about the output pulses is transferred to a master memory of a contents addressable memory at an optional timing from outside. The contents of that master memory are copied to a slave memory in response to copy enable signals transmitted from a copy enable device. The copy enable signals are transmitted whenever a predetermined number synchronizing signals showing an end of the pulse period are generated from the interval timer. The contents addressable memory reads out the output control command of the output pulse from a slave memory when the timer value of the interval timer coincides with the time data of the slave memory. The output control circuit transmits output pulses which correspond to the control command read out as described above. As a result, if the output time data is reloaded at an optional timing from outside, the generation of an error in the pulse width of the output pulse can be prevented. Furthermore, the load of the CPU can be reduced.

    摘要: A digital pulse processing device is capable of selecting desired precision. The digital pulse processing device includes a counter group for counting pulses output from a pulse output device, the counter group having a plurality of counters A and B that can be separated from and coupled with each other, a mode control circuit for instructing separation and coupling of the counters A and B, and a control circuit for separating and coupling the counters A and B in accordance with the instruction of the mode control circuit. An overflow condition of the free-run counter B is detected using an overflow flag. Detection of an overflow is conducted by setting the flag when an overflow condition has occurred twice or more. The flag is reset by rewriting the state of the flag by a software. An overflow condition which has occurred for the first time is detected in the conventional manner and is treated as carry or borrow. A register is provided to hold the value of the counter B when a microcomputer reads in the counter B. In this way, even when .DELTA.A(i)=0, speed detection operation can be executed using the value of the counter B obtained synchronously with the counting of the counter A.

Both the current reference generator and the current control circuit are processed digitally by the same arithmetic unit.

    摘要: A control apparatus of an electric motor vehicle includes a device for operating an initial magnetic pole location based on three phase magnetic pole location signal pulses of a permanent magnet electric motor upon starting the electric motor vehicle, a device for operating a magnetic pole phase of the permanent magnet electric motor on the basis of the initial magnetic pole location, a rotation pulse of the permanent magnet electric motor, and a correction value which are operated with the rise and fall of the three phase magnetic pole location signal pulse after the starting, a device for determining a current to be supplied into the permanent magnet electric motor based on the magnetic pole phase and a torque reference value, and a device for correcting the magnetic pole phase when a predetermined one of the three phase magnetic pole location signal pulses rises or falls. In such an apparatus, as the magnetic pole phase is revised on the basis of the magnetic pole location signal of any one phase among the three phase magnetic pole location signals, the revising frequency of the magnetic pole phase becomes low and the microcomputer processing burden when the magnetic pole phase correction device operates in a high-speed rotation can be reduced.

    摘要: In a controller for an electric vehicle, a voltage current phase difference calculating circuit calculates a vector phase .theta..sub.c from a voltage command value and the primary current of an alternating current motor. The vector phase .theta..sub.c is input to a second voltage command circuit which calculates a second d-axis voltage command value and a second q-axis voltage command value using the vector phase .theta..sub.c and d-axis and q-axis current differences. By correcting the voltage command value using the second d-axis and second q-axis voltage command values, the stability of the current control system is improved. By controlling the electric vehicle using such a system, a stable current control can be attained even when the electric vehicle is driven under a regenerative running state or a weak magnetic field control state.

    摘要: An electric vehicle torque controller has a torque calculating unit and an actual torque detecting unit. The calculated torque is compared with the actual torque to generate a torque compensation value, which is converted to a torque current signal. The torque current signal is used to generate a slip frequency, which is added to an output of an angular speed detector and used to set a secondary magnetic flux value. A secondary magnetic flux signal is generated according to the secondary magnetic flux value and the torque current signal. A secondary magnetic flux estimating unit generates an estimated secondary magnetic flux value, which is used to determine the exciting current. Primary motor current is controlled in response to the exciting current, the torque current, motor speed and slip value.
