Problems solved by technology

The first method belongs to the theoretical verification of the algorithm, and the experimental condition is the simulation under ideal conditions. This method has the advantages of convenient and fast establishment of the simulation model, but at the same time, this method also has the problem of not being able to apply the processing results to the servo in real time. In the system; the second method is a servo system based on a special DSP chip, which has high precision, but the modification of the algorithm and algorithm parameters and the change of the load need to spend a lot of time and energy, and it is not suitable for the test
