摘要： A constant travel speed control apparatus is for use in a vehicle and utilizes time delay control which is a kind of adaptive control for estimating an unknown term. A plurality of targeted paths, each having a certain waveform, for causing the actual speed of the vehicle to converge on a target speed are provided and an error vector is defined on the basis of the paths. The actual speed of the vehicle can be made to converge on the target speed thereof with a constant convergence performance along a target path in spite of the fluctuation of vehicle dynamic characteristics.

摘要： Qualitative relations between changes in a charge voltage, a developer bias voltage and an exposure light intensity control voltage and change in an image density are investigated in advance, and a density error is derived by a difference between the density of the image of a reference mark and a target density. Respective variations of the charge voltage, developer bias voltage and exposure light intensity control voltage are derived on the basis of the qualitative relations and the density error, and thereby the charge voltage, developer bias voltage and exposure light intensity voltage are changed so as to decrease the density error.

摘要： A method for position-sensorless motor control is provided, wherein a rotor-position estimation current signal is superimposed on the &ggr;-axis direction component of a target current vector representing target currents of stator windings. The period of the current signal is an even multiple of a PWM carrier period and varies at random. The amplitude of the current signal increases with the amplitudes of the target currents. An even number of samples are obtained from the &dgr;-axis direction component of a current vector representing detected currents of the stator windings in each period of the current signal. A discrete Fourier integration of the samples determines the amplitude of a current response to the current signal in the &dgr;-axis direction. The &ggr;-axis direction is corrected so that the current response substantially shrinks to zero in the &dgr;-axis direction.

摘要： A discrete rotor position estimation method for a synchronized reluctance motor is provided. A d.c.-link voltage Vdc and a phase current Iph are sensed. A flux-linkage λph of an active phase is calculated from the sensed d.c.-link voltage Vdc and the sensed phase current Iph. The calculated flux-linkage λph is compared with a reference flux-linkage λr. The reference flux-linkage λr corresponds to a reference angle θr which lies between angles corresponding to aligned rotor position and non-aligned rotor position in the synchronized reluctance motor. An estimated rotor position θcal is obtained only once when the calculated flux-linkage λph is greater than the reference flux-linkage λr.
