Abstract:
The scheme proposed by U. Hartmann et al. has been improved in this paper on the gain
adaptation laws. A concise, reasonable model under parameter estimation, and identification
algorithm are proposed. Computation workload has been decreased to 50% of the original.
Thus, the quality of the parameter estimation is satisfactory, and the adaptation laws are more
practical. The microcomputer implementation of the scheme is studied. Digital-anolog hybrid
simulation results show that such a scheme possesses simplicity of algorithm, and it can be easily
realized from an engineer's point of view. The software satisfies accuracy, real time and flight
control quality requirement.
