Abstract: | In this paper, a Self-Tuning Regulator (STR), one of the adaptive control strategies, is applied to the GLA system of a large civil aircraft. Two types of STR are introduced. For Algorithm 1, the restriction that the number of the inputs must be equal to that of the outputs is imposed. On the contrary, for Algorithm 2, this restriction is released. These two algorithms are applied to alleviate the gust response of aircrafts, firstly a rigid aircraft and secondly a flexible one. In consequence of simulations, it is found that the STR can alleviate the gust response of aircrafts favorably. A STR is more effective to alleviate response to a discrete gust than to a continuous gust. In spite of the inaccurate estimation of system parameters, the STR works well. Generally, the proposed STR's show better performance for a rigid aircraft than for a flexible one. However, even for the latter, by choosing initial values of parameters appropriately, we can get good results. |
