Patent EP-0330477-A2 (EP)
Inventor: MUKAI TADAYOSHI
IPC: H02P27/08
Filed: 1989-02-23
Abstract: An improved induction motor control system utilizes an inverter  4  supplying a variable frequency AC voltage to drive the induction motor  5 , and volt/frequency (V/F) control section  10  controlling the inverter  4  to produce a suitable voltage and frequency in a predetermined relationship therebetween. Power factor detecting section  20  is included to detect a power factor phase angle between the motor current and the inverter output voltage as indicative of an amount of load imposed on the motor  5 . The detected power factor phase angle is compared with a predetermined phase angle which is a frequency dependent angle indicative of a standard load at a given frequency, in order to provide a control output. In response to the control output the V/F control section  10  alters the inverter output voltage out of the predetermined relationship with the frequency for improving motor efficiency. Thus, the detected load (i.e., power factor phase angle) can be evaluated, by simple comparison with the standard load level (reference angle), for controlling the inverter to effect the output voltage or motor torque regulation in response to the load imposed. Also, the frequency dependent reference angle can well compensate for a significant phase shifting of the motor current in relation to the inverter output voltage as seen in the low frequency range, enabling a consistent motor control even in the lower frequency range.

Abstract: A scrambling/descrambling apparatus has a data memory (32) for storing a data word, a bit invert flag, and numerical data. A bit shift operating section (4) performs, on receiving a bit of data to be outputted or a bit of input data, a bit shift operation with that bit and stores resultant data in the data memory (32) in the form of a first data word. A randomizing/derandomizing section (1) randomizes or derandomizes the input data by using the first data word and based on a generating polynomial and, depending on a state represented by the bit invert flag, inverts the bit of the data to be outputted to develop output data. A count processing section (2) increments or decrements the numerical value stored in the data memory (32) and, depending on the numerical value, selectively sets the bit invert flag to a predetermined state. A count controlling section (3) replaces the numerical value with a predetermined initial value on the basis of the first data word and bit invert flag. The data memory (32) holds a second and a third data word (dw0, dw1), bits of which corresponding in position to a particular bit (B8, B9, B12) of the first data word are a ZERO and a ONE, respectively. The count controlling section (3) reads selectively either one of the second and third data words (dw0, dw1) out of the data memory (32) depending on the value of the bit which is inputted to the bit shift operating section (4), Exclusive-ORs the data word (dw0, dw1) read out and the first data word, performs a masking operation with a data word (a1) resulting from the Exclusive-ORing for validating a bit corresponding in position to the particular bit position (B8, B9, B12) of the first data word while invalidating the remaining bits, and replaces the numerical value with the initial value when a data word (a2) resulting from the masking operation is indicative of a ZERO or when the bit invert flag is in the predetermined state. Alternatively, the count controlling section (3) may read the first data word out of the data memory (32) and, depending on the value of the bit which is inputted to the bit shift operating section (4), NOT or transfer the first data word, performs a masking operation with a data word (a1) representative of a result of NOTing or that of transfer for validating a bit corresponding in position to the particular bit position (B8, B9, B12) of the first data word while invalidating the remaining bits, and replace the numerical value with the initial value when a data word (a2) resulting from the masking operation is indicative of a ZERO or when the bit invert flag is in the predetermined state.
