Pulsar navigation has shown its great potentiality in autonomous navigation for orbit satellite and deep space spacecraft. Relative navigation using pulsar signal has shown its benefit in recent years, and higher performance has achieved in some studies. The proposed method in this paper uses X-ray and radio spectrum of pulsars to implement the relative navigation and the DSN range measurement are...
This paper presents the hardware implementation of PID control algorithm based on FPGA. The design adopts the three levels pipeline and ping pong operation in order to strike a balance between the speed and the exhausted FPGA resources. In the process of verifying the design performance, the paper introduces a sine micro stepping driver system model of stepper motor. This model needs PID control to...
