A new direct torque control method which is quite different from conventional vector control is presented. Following results are obtained by testing the experimental system; 1.Impact torque of 20 times of the rated torque is obtained. 2.The frequency response at the sinusoidal rated torque is about 2 kHz. 3.Time constant of 4 ms have been achieved for the speed step response from -500 rpm to 500 rpm. 4.Decoupling control between torque and flux of the primary winding can be easily realized. 5.Full digital control is economically realized by using DSP (TMS320-10).Ultra-wide range speed control based an the principles of impulsive torque drives is proposed and following results are obtained; 1.Ultra-low speed of 1 rev/day and speed variation of <plus-minus>0.1 rev./hour are experimentally realized. 2.Wide speed control range of 1:2,000,000 is also obtained by using its principle. 3.The speed drift at rated torque is under 1 rev/week which is determined by the integrator of the drift of the P-I circuiFinally, high resolution positioning control is challenged by using above impulsive torque drives and sliding mode control. 1.Full digital circuits are constructed by DSP and a high resolution position sensor. 2.The accuracy of the position obtained by control is 1 sec.(1/1296000 rev) 3.Auto tuning to compensate the variation of the load constants is realized by changing the slope of the sliding line. 4.Small position error of 40 sec at the impact load is obtained by P-I control within 0.1 sec. These results are all world records and provided to be very promising and skillful techniques. Drive systems using above techniques have been applied to HSST drives and industrial servo systems above 200 sets.

提出了一种不同于传统矢量控制的直接转矩控制方法。通过对实验系统的测试，得到了以下结果：1.冲击力矩为额定扭矩的20倍。2.在正弦额定转矩处的频率响应约为2khz。3.从-500转到500转的速度阶跃响应时间常数为4毫秒。4.实现了一次绕组转矩与磁通的解耦控制。5.采用DSP （TMS320-10）经济地实现了全数字控制。提出了基于脉冲转矩驱动原理的超宽范围调速方法，并取得了以下结果：1.实验实现了1转/天的超低转速和<±>0.1转/小时的转速变化。2.利用其原理，还获得了1:20 000的宽调速范围。3.在额定转矩下的速度漂移小于1转/周，由P-I电路的漂移积分器决定。最后，采用上述脉冲转矩驱动和滑模控制对高分辨率定位控制提出了挑战。1.全数字电路由DSP和高分辨率位置传感器组成。2.通过控制获得的位置精度为1秒（1/1296000转）通过改变滑动线的斜率，实现了对载荷常数的自整定补偿。4.在冲击载荷下，P-I控制在0.1秒内，得到了40秒的小位置误差，这些结果都是世界纪录，是非常有前途的技术。采用上述技术的驱动系统已应用于200台以上的HSST驱动和工业伺服系统。
