Embodiment Construction
[0043] Such as figure 1 As shown, a general miniaturized digital electric steering gear controller includes a control module, a power supply module, a digital communication module, a signal conditioning module, an AD sampling module, a storage module, a steering gear drive module, a displacement detection circuit and a current detection circuit.
[0044] Such as figure 2 As shown, the control module uses FPGA as the main control chip, including trajectory generation module, parallel-to-serial module, steering gear algorithm module, serial-to-parallel module, steering gear drive control module, and fault detection and protection module.
[0045] Among them, the power supply module is respectively connected with other modules, isolates the input primary DC bus voltage and converts it into a voltage value required by each module, and supplies power for the normal operation of the other modules. The power module includes two-way isolated DC / DC power module and four-way non-isolate...
