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.
