Abstract


The intermeshing motor reducer and servo motor integrated into a a new reluctance class motor . Meshing motor due to its structure and operating characteristics of the motor characteristics and control of traditional motor there are obvious differences , this article from the motor characteristics detection , modeling and control strategies to study it . Meshing motor magnetic circuit there is a serious saturation nonlinear The electromagnetic characterization directly affect the analysis, design and application of the motor , measured the accurate flux linkage characteristics and motor torque characteristics , accurate modeling of the motor and high important basis for performance control . In this paper, the the indirect flux measuring principle, design , inductance, torque characteristics of the engaging prototype motor flux is obtained by calculating the analysis based on the characteristics of a DSP (digital signal processor) detecting means . Establishing engaging motor model is to improve the control key to the performance of their systems . In this paper, based on the actual measurement of motor flux and torque characteristics , establish the linear model of the motor , the quasi-linear and nonlinear models . Static performance analysis , create the conditions for the realization of the system parameter optimization, Control Strategy , the system automatically . The simulation results and experimental waveforms compared to verify the validity of the model . According to the characteristics of the meshing motor , design -based DSP full digital controllers . Controls the drive circuit , the design of the power converter , a detailed analysis . Control circuitry to TMS320F2407 controller core, including the power supply circuit , a current voltage detection circuit , an overvoltage current protection circuit and the position, velocity detection circuit, communications circuit module . The test results prove that the system is simple , practical , high operating efficiency . On the basis of theoretical analysis , meshing motor control strategy : chopped current control strategy (CCC), the angular position of the control strategy ( APC ) , and carried out a detailed analysis of the feasibility of the program is verified by simulation . . Design the system control software for modular programming and control software flow chart is given , and motor experiment platform on the validation of these two control strategies .
