Article Synopsis
- The paper discusses a method for identifying the aerodynamic coefficients of a spinning projectile, specifically a missile, using gasodynamic engines and a measurement inertial unit based on Newton's law of motion.
- The identification process employed the maximum likelihood principle within the wavelet domain and was also tested in the time domain to compare results.
- Results indicated that while noise-free data led to highly accurate aerodynamic coefficient estimates, noise introduced some inaccuracies, especially in the time domain method, whereas wavelet-based estimates remained fairly accurate despite the noise.
The article presents the analysis of the impact point dispersion reduction using lateral correction thrusters. Two types of control algorithms are used and four sources of uncertainties are taken into account: aerodynamic parameters, thrust curve, initial conditions and IMU errors. The Monte Carlo approach was used for simulations and Circular Error Probable was used as a measure of dispersion.
