  • This paper presents a study on DSP(TMS320F240) controller design for multi-axes transportation system using BLDC servo motor. This BLDC servo motor controller was realized with DSP(Digital Signal Processor) and IPM (Intelligent Power Module). The multi-axes transportation system needs torque, speed, position control of servo motor for variable action. This paper implements those servo control with vector control and space vector modulation technique. As CPU of controller DSP(TMS320F240) is adopted because, it has PWM(Pulse Width Modulation) waveform generator, A/D(Analog to Digital) converter, SPI(Serial Peripheral Interface) port and input/output port etc. The controller of multi-axes transportation system consists of 3-level hierarchy structure that main host PC manages three sub DSP system which transfer downword command and are monitoring the states of end servo controllers. Each sub DSP system operates eight BLDC servo controllers which control BLDC servo motor using DSP and IPM Between host system and middle digital signal processor communicate with RS-422, between main processor and controller communicate with SPI port.

  • 직류직권모터는 전동지게차와 같은 물류용 전동차에서 사용되는데, 우수한 기동 토오크를 가지는 반면에 파라미터의 열적, 변화가 심하고 마찰과 부하의 비선형성이 존재해 기존의 제어기로는 만족할 만한 성능을 내지 못한다. 본 논문에서는 이를 해결하기 위해 퍼지제어기를 사용한다. 퍼지제어기는 변수의 애매성에 바탕을 두고 제어하기 때문에 이러한 비선형성에 대해 강인하나, 소속함수의 결정과 퍼지규칙의 선정이 어려우며, 체계적인 방법이 존재하지 않는다. 이러한 퍼지제 어의 결점을 해결하기 위해 소속함수는 유전 알고리즘을 통해 자기동조 시키며 퍼지규칙은 오차와 오차변화율의 위상평면을 이용하여 결정한다. 실용성을 검증하기 위해 TI사의 DSP TMS320F240을 이용해 실시스템에 적용했으며, 이를 통해 부하의 변동 및 기준 속도의 변화에도 잘 대처함을 알 수가 있었다.

  • This paper presents a ripple reduction of BLDC motor using TMS320F240. A fault of permanent magnet(PM) BLDC motor possible to miniaturization and high-output is to be difficult to reduce speed-ripple at low speed region. An existing solution is to be use of PWM waveform by PI control with computing control angle of 60$^{\circ}$. The new family of DSP controllers provides a single chip solution by integrating on-chip not only a high computational power but also, all the peripherals necessary for electric motor control. This paper gives an advanced solution of the SVPWM technique for the purpose of reducing control angel rather than 60$^{\circ}$. This technique gives an excellent speed ripple characteristic.

  • In this paper, we propose a new control scheme for a PWM inverter using digital control. Digital control has various advantages in comparison with conventional analogue control. It can achieve high frequency switching of inverter and can be little influenced for temperature variations and aging of devices. This digitally-controlled PWM inverter is implemented using a Digital Signal Processor(DSPTMS320F240). The simulation results are given to verify the DSP based PWM inverter design and implementation.
