Description
Technical field
The invention belongs to electric machines control technology, particularly a kind of motor multiplex control system and control method thereof of utilizing Digital Signal Processing and virtual instrument technique to combine, combine by digital processing unit and computer platform, realizes the efficient control of motor.
Background technology
At present, it is to adopt digital signal processor (DSP) as the core of control system that motor digital servo commonly used is controlled, and the quantity of state when moving by gathering actuator is processed in the DSP internal arithmetic, goes to control the actuator operation according to certain algorithm.Shown in Figure 1 in its principle such as Figure of description.But because computing and the processing speed of DSP has certain limit (as TI company's T MS320F28X type DSP commonly used, its maximum processing speed is 150 MIPS), be difficult to motor is adopted more complicated, more accurate control algolithm (controlling Processing Algorithm etc. as fuzzy control Processing Algorithm, adaptive control Processing Algorithm, ANN Control Processing Algorithm and sliding formwork).On the other hand, because insufficient memory in the sheet of DSP is large, and the control algolithm of comparative superiority not only needs efficient operational capability, and needs relatively large memory space, and this also makes independent DSP control system can't realize the complex control algorithm.
