H-infinity loop shaping: the Bell 205 helicopter case study
A. J. Smerlas, I. Postlethwaite and D. J. Walker
Abstract
The objective of this paper is to describe an
H-infinity control law for the Bell 205 fly-by-wire helicopter. The
controller was designed using robust stabilisation and a loop shaping
procedure in order to provide an Attitude-Command-Attitude-Hold (ACAH)
response type. Ground-based piloted simulations were conducted on the
Large Motion System (LMS) within the Advanced Flight Simulator complex
at the Defence Evaluation and Research Agency (DERA),
Bedford. In-flight evaluation was performed on the National Research
Council of Canada's Bell 205 Airborne Simulator which gave Level 2
desired Cooper Harper ratings.
