On design of digital H/sub ∞/ filters
Xiang Chen, A. Tahmasebi · 2002
In this paper, design approaches for digital H/sub /spl infin// filters are discussed. In particular, two design methods, called indirect and direct design respectively, are proposed to develop a class of digital H/sub /spl infin// filters. The indirect design is a pure discrete-time method, while the direct design develops digital H/sub /spl infin// filters directly for continuous plants using the so-called lifting technique and taking intersample information into account. Possible selection of a special digital H/sub /spl infin// filter from the admissible class is also discussed.
