This paper presents a SPMSM(Surface-mounted Permanent Magnet Synchronous Motor) servo drive system using high performance TMS320F2812 DSP for the industrial application. The DSP(Digital Signal Processor) Controller enables an enhanced real time algorithm and cost-effective design intelligent for only exclusively motor drives which can be yield enhanced operation, fewer system components, lower control system cost, increased efficiency and high performance. The suggested system contain speed and current sensing circuits, SVPWM(Space Vector Pulse Width Modulation) and I/O interface circuit. The developed servo drive control system showns a good response characteristics results and high performance features in general purposed 400[w] machine. This system can achieve cost reduction and size minimization of controllers.

In this paper, the high precision position control of AC Servo motor for semiconductor equipment is studied. The control system was implemented using TI DSP TMS320F2812 which has 150 MIPS speed for next generation motor control. The controlled 100W PMSM motor has 2,500 ppr optical incremental encoder. The control system has speed controller and current controller to control the motor position. The encoder pulses are divided into 4 times, which has 10,000 ppr and the motor system has the position accuracy of 1/10,000. If the resolution of the encoder is increased, the resolution of the position control will be increased.

This paper presents a study on the DSP(Digital Signal Processor) controller for the PBW(power-by-wire) system using BLDC(Brushless Direct Current) servo motor pump. The PBW hydraulic actuator was realized with hydraulic pump driven by BLDC servo motor, hydraulic cylinder and controller. This PBW system needs speed control of servo motor for linear thrust action of hydraulic cylinder. This paper implements a servo controller with vector control algorithm and MIN-MAX PWM technique. As CPU of a controller, TMS320F2812 DSP was adopted because it has PWM waveform generator, A/D converter, SPI(Serial Peripheral Interface) port and many input/output port etc.

최근 산업 분야에 걸쳐서 고속, 고정밀도의 요구사항에 따라, 회전 모터와 볼 스크류, 벨트를 이용한 직선구동방식보다 빠르고 정확하며, 효율이 높은 직접구동 방식의 리니어모터 및 컨트롤러의 개발이 요구되고 있다. 이런 상황에 고속 연산을 수행할 수 있는 DSP(Digital Signal Processor)의 사용이 불가피하며, 기존의 칩들은 A/D변환기, PWM발생장치 등이 내장되지 않아 제어장치의 부품 수증가 및 복잡성을 피할 수 없었다. 따라서 본 논문에서는 SVPWM(Space Vector Pulse Width Modulation) 및 QEP(Quadrature Encoder Pulse) 회로와 PWM 발생기, 12bit의 고속 A/D변환기, 파워 드라이버보호회로 등을 내장한 TMS320F2812 DSP를 사용하여 반도체장비분야, 자동화분야 등에 사용되는 LBLDCM의 제어를 가능하게 만들었다. 또한, 기존의 DSP 시리즈 보다 연산속도가 고속화되어 고속연산에 의한 시간적 제한을 극복 할 수 있게 되었고, 제어에 필요한 하드웨어적인 기능들을 내장하고 있어서 주변회로가 필요 없게 되었다. 따라서 하드웨어의 간소화와 개발 시간의 단축 및 신뢰도의 향상과 모터 효율의 향상을 가져오도록 하였다. 제안된 제어장치는 제작되어, 실험을 통하여 그 타당성을 입증하였다.

This paper presents an implementation of efficiency optimization of reluctance synchronous motor (RSM) using a neural network (NN) with a direct torque control (DTC). The equipment circuit considered with iron losses in RSM is analyzed theoretically, and the optimal current ratio between torque current and exiting current component are derived analytically. For the RSM driver, torque dynamic can be maintained with DTC using TMS320F2812 DSP Controller even with controlling the flux level because a torque is directly proportional to the stator current unlike induction motor. In order to drive RSM at maximum efficiency and good dynamics response, the Backpropagation Neural Network is adapted. The experimental results are presented to validate the applicability of the proposed method. The developed control system show high efficiency and good dynamic response features with 1.0 [kW] RSM having 2.57 inductance ratio of d/q.
