FIR notch filter design based on double phase-shift combination all-phase method;

To reduce the hardware cost of notch filter with the notch frequency point accurately controlled as far as possible,a novel notch filter design algorithm combining the techniques of all-phase filtering and frequency response masking(FRM) is presented.

FIR filter design based on adaptive quantun-behaved particle swarm optimization algorithm;

FIR filter design based on all-phase amplitude-frequency characteristic compensation;

2-D Filter Design Method Based on McClellan Transformation;

Conclusion The proposed algorithm can be used for ranking selection filter designing in the unstable s.

Development of a kind of software to identify the parameter of PID model and the filter parameter of a closed-loop PID system with NLJ;

In this paper the filter design problem in control theory is changed into solving of a linear matrix inequality, and the filter design problem with satisfying varies of performance targets is converged into solving problem of the linear matrix inequalities.
