Mathematical problems in engineering, 2013, 1-5. | Series/Report no.: | Mathematical problems in engineering | Abstract: | Pulse-width pulse-frequency (PWPF) modulators are widely used in spacecraft thruster control. Their dynamic characteristic is still lack of effective analysis tools. This paper presents a fractional describing function method to describe the frequency characteristics of PWPF. A frequency-dependent gain and phase shift are clearly described by fractional-order expression, and the fractional-order behaviors depict the nonlinear properties of PWPF modulators. This fractional describing function method can also be applied to other kinds of modulators. | URI: | https://hdl.handle.net/10356/101418 http://hdl.handle.net/10220/18661 |
