| Popis: | Current approaches to in-flight failure accommodation are focused either on failures of sensors or control surface actuators. Some results also focus on simultaneous sensor and actuator failures. However, there are apparently no results for the case of engine actuation failures when the engine dynamics are slow and its output is not measurable. Hence, the stability proofs for the case of accommodation of simultaneous actuator, engine, and sensor gain failures are not available. On the other hand, overall system stability is crucial in preventing loss of control under flight-critical failures. In this paper, a stable adaptive approach to simultaneous sensor, actuator, and slow-engine gain failure accommodation in flight control is proposed. The approach is broken into two parts: 1) design of a stable adaptive reconfigurable control scheme for accommodation of actuator and engine gain failures in the case of slow-engine dynamics and nonmeasurable engine output, and 2) stable adaptive control design extendin... |
