First , introduced its working principle and basic structure, as well as its system Matlab simulation, and secondly from the hardware design of the main aspects of the entire control circuit has been designed, and finally introduces some simple software algorithm and control algorithms. In terms of hardware, I designed the power circuit, detection circuit, conditioning circuit, the cutoff frequency is set to 500Hz, And the components in the circuit design parameters. The power supply circuit, conditioning circuit were simulated in Multisim, And I put them into a circuit board. Then drive on the circuit and optical isolation for the hardware design.
