In fact the term (2,1) is the change in the pitching moment due to a small change in the vertical speed of the aircraft (Chapter 4). For the static stability of the aircraft, this term should be negative. 10 Block diagram for the state space model. and have obvious physical meaning. In addition, the elements of matrices A and B have physical meaning, as shown in Chapter 5. 10. 10 that the variables w and q _ q) _ and hence signify internally inherently provide some feedback to state variables (w, connected control system characteristics of dynamic systems.

Events or occurrences leading to FL are (1) the light could be dim, (2) the day could be bright with a certain degree of brightness, (3) the day could be cloudy with a certain degree, and (4) the weather could be warm or cold. Thus, FL allows for a degree of uncertainty and gradation. Thus, truth and falsity (1 or 0) become the extremes of a continuous spectrum of uncertainty. This leads to multivalued logic and the fuzzy set theory [7]. , triangular form. Several types=forms of membership function are available in MATLAB FL toolbox.

Let u(k) be a random Gaussian (noise) sequence with zero mean and unit standard deviation. Compute SNR as 20 log 10(var(y)=var(u)) (in MATLAB). 36 Flight Mechanics Modeling and Analysis Solution Generate Gaussian random noise sequence by u ¼ randn(500,1). Then standardize the sequence by un ¼ (u À mean(u))=std(u). 9467. 8958e À 017 and std ¼ 1. 11a. 11b). 1754. 0525 and both are within unit circle in the z-domain=complex plane. 0; (b) the stable time series y; (c) the unstable time series y. 37 Mathematical Model Building is greater than 1, then the time series will be unstable.
