Parametrically Optimal Control for the UH-60A (Black Hawk) Rotorcraft in Forward Flight
MetadataShow full item record
New techniques for the design of rotorcraft flight control systems (FCS) to meet hover flight condition handling qualities requirements (HQR) have recently been developed. These techniques are based on multicriterion optimization as implemented in the optimization package CONSOL-OPTCAD (C-O). Further development of these methodologies applicable to the design of a FCS to meet forward flight HQR is presented herein. The forward flight design methodology is applied to the design of a FCS for the Advanced Digital Optical Control System (ADOCS) UH- 60A Black Hawk helicopter in forward flight at 80 knots. The controller parameters have been optimized to meet the ADS-33C forward flight specifications. Utilizing this approach, an optimal controller based on minimum actuator control energy has been obtained and trade-off studies have been performed.
