Induction Motor Direct Torque Control and Digital Simulation
System of systems theory, combined with the motor model, it can be digitally simulated. Simulation block diagram is as follows: the discrete simulation of the mathematical model used is as follows: Simulation block diagram of Figure 5 Volume 20 No. 3 Pan Feng et al: Induction Motor Direct Torque Control and Digital Simulation 239R, R ~ I f community dioxin 2 Lu] : * A ~ '/' rok a] * having only one ~\This is simulated, the software is rich package, eliminates many tedious low level design, and simple to use. The results clear, control system design is a powerful tool in this case, = 0.0001 (a) transfer Moment response curve simulation results: These results show that the system torque response is accurate, fast, any case of the magnetic field has been established, the torque response is almost no time. flux linkage established in the starting soon, to the amount of passengers magnetic the chain in the dynamic and static process approximately constant. The only guarantee the dynamic speed response quickly when (b) Flux response curve (c) speed response curves of simulation results in Figure 6, but also guarantees the stability of static From Figure 6 (c) can be seen in the dynamic process of response is a straight line, indicating that a ll ● the provision of electricity + +240 Taiyuan Heavy Machinery Institute 1999 machine is the maximum torque starting from 0 increases the speed to 5O electrical angle requires only 16 milliseconds, and once the motor reaches a given speed, will remain approximately constant, fluctuating very little,[link widoczny dla zalogowanych], show a great immunity. Simulation of the motor parameters are as follows: P A = 3.5kw, Vm = 220V, P = 1,[link widoczny dla zalogowanych], R = 0.55n, R = 0.3992, L = 70.32mH, L,[link widoczny dla zalogowanych], = 68.93mH, L = 65.OOn ~-I, J = 0.056kg., 00 = 0 .572 wI) .2 This article describes the work on the principle of direct torque control was introduced, and the combination of motor model simulation system is constructed it for the digital simulation results show that the method has good dynamic and static performance. But it also there are some problems, such as: low-frequency sawtooth ripple torque response, low distortion when the flux and so on. Further experiments and improvements in progress.
