In turboprop aircraft, the low-frequency noise field created by propellers is major contributor to interior vibro-acoustic field, which determines a passenger’s discomfort. This paper deals with experimental assessment of an active control (ANC) system for cabin seat headrests using two loudspeakers placed on both sides head create local zone quiet around ears. To deal time-varying disturbances...

The problem of using engine thrust differentials to compensate for rudder and aileron failures in aircraft flight control is addressed in this paper in a new framework. A nonlinear aircraft model that incorporates engine differentials in the dynamic equations is employed and linearized to describe the aircraft’s longitudinal and lateral motion. In this model two engine thrusts of an aircraft ca...

This paper presents a comparative analysis of two intelligent reference learning techniques to achieve better performance of pitch control of an aircraft. Fuzzy Model Reference Learning Controller (FMRLC) and Radial Basic Function Neural Controller (RBFNC) are designed for pitch control of a FOXTROT fighter aircraft. These controllers utilize a learning mechanism, which observes the plant outpu...
