Abstract

A dynamically configurable intelligent controller of a machine tool based on DSP/FPGA and control method thereof are disclosed. The intelligent controller includes a DSP/FPGA information processing module, a data input module, an output execution module and an embedded central processing system module. The DSP/FPGA information processing module includes a hardware reconfigurable information sampling unit, a digital signal processing unit, a hardware reconfigurable algorithm unit, a hardware reconfigurable control information output execution unit and a data storage unit. The DSP/FPGA information processing module configures hardware units according to an intelligent control strategy file created based on the intelligent control needs to generate an intelligent control algorithm graph. The intelligent controller according to the present disclosure can, based on the control needs of the machine tool, dynamically configure the input and output hardware and the algorithm hard ware, and reconfigure the I/O connection and the algorithm module to generate an intelligent control algorithm graph. The intelligent controller also can dynamically output control instructions.
