Abstract:

We present a concurrent execution method for contral of large quantity displacement actuators for extremely large telescope based on FPGA technology, and the key is to build a control module which generates the control signals of displacement actuators. The construction and simulation using low-level verilog hardware language is described in detail, and the implementation of hardware and software systems is also described.

Key words: enormous telescope, FPGA, displacement actuator, concurrent execution, control module
