A method of implementing controls of chopper for HIRFL-CSR (Heavy Ion Research Facility of Lanzhou and Cooler Storage Rings) is introduced. This method is based on an ARM and DSP co-operation system. The control algorithm of this method is based on a data structure which is defined and implemented in the DSP module. Output data is created by the control algorithm and the actually pulse output is triggered by a timer which is achieved through a logic circuit actualized in a FPGA chip. The results show that the method is flexible and the control system matches the chopper regulating requirements. | ||
