摘要： Disclosed is a method for suppressing a speed ripple occurring during an operation of an AC motor by using a torque compensator based on an activation function. The method includes the steps of calculating a speed error ωerr based on a reference speed ωref and an actual speed ωact; calculating a controller output Trm by using the speed error ωerr as an input of a PI control and an operation of a compensated torque Tcom; and determining a torque variation based on the controller output Trm and a reference torque Tref and operating the torque variation in relation to an anti-windup gain Ka to use torque variation as an input of an integral (I) control. The method suppresses the speed ripple by compensating for the torque ripple through a controller which calculates the compensated torque by taking the signs of the speed error and the differential speed error into consideration.

摘要： Disclosed is a hybrid pole bearingless switched reluctance motor (BLSRM). The BLSRM includes a stator provided with windings, a rotor rotating about an axis when current is conducted to the windings. The rotor includes a plurality of rotor poles extending radially outward, and the stator includes a plurality of stator poles extending radially inward. The windings include suspending windings to generate radial force for the rotor and torque windings to generate torque. The suspending windings are mutually separated from the torque windings. Through the use of the hybrid pole BLSRM, a stator pole generating the radial force can be controlled independently from the stator pole generating the torque by separately arranging the stator pole generating the radial force and the stator pole generating torque based on the analysis of radial force and torque characteristics according to the position of the stator poles.

摘要： Disclosed is a dead-time compensation method of a 3-phase inverter using an SVPWM scheme. The dead-time compensation method includes generating a switching signal having dead-time with respect to the power semiconductor switches of the upper and lower arms in order to obtain a predetermined output through the SVPWM scheme, detecting medium phase current from each phase current output through the switching signal, determining polarity of the medium phase current, and generating a switching signal by calculating switching time in order to compensate for time to apply effective voltage according to the polarity of the medium phase current. Through the dead-time compensation method, the distortion of the output voltage and the reduction of voltage having a fundamental wave in the output voltage, which are caused by the dead-time, are minimized through the switching of compensating for the time to apply effective voltage based on the polarity of the load current.

摘要： A system for directly and instantaneously controlling the exciter of a generator. A voltage error calculator calculates a voltage error of output voltage of the generator which is regulated by an instruction voltage and a time constant. A switching signal generator generates switching signals in response to the voltage error. An exciter controller controls the exciter in response to the switching signals. Thus, the system can induce the maximum response characteristic of a power converter only by setting the time constant of a controller without a complicated design for determining gains of the controller. Further, the system can considerably inhibit overshoot from occurring in a transient response state.

摘要： A polymer electroluminescent device is provided. The device includes an anode, a light-emitting layer, a cation-containing water-soluble polymer layer and a cathode formed in this order on a substrate wherein the cation-containing water-soluble polymer layer is formed by wet coating. The cation-containing water-soluble polymer layer as a secondary thin film layer is not dissolved in a solvent for the formation of the underlying light-emitting layer to prevent intermixing between the two layers, thereby enabling the formation of a multilayer structure by wet coating. In addition, the cation-containing water-soluble polymer layer attracts electrons injection from the cathode by an attractive Coulomb force to effectively increase the mobility of the electrons while blocking high-mobility holes from the anode at an interface between the light-emitting layer and the water-soluble layer. Further provided is a method for fabricating the electroluminescent device.
