    Abstract
  • The method of error compensation for inertial elements in navigation system based on fuzzy optimal algorithm is presented. Its essential idea is combining genetic algorithm (GA) with fuzzy logic reasoning, preserving strong whole searching capability of GA and acting membership function as genetic individual. Consequently, the fuzzy rules are optimized by means of selection, crossover and mutation operation and so on, realizing the optimization of fuzzy rules on line. And then on the basis of optimized fuzzy rules, the genetic operation and parameters are adjusted on line again and the fuzzy rules are further optimized, which makes fuzzy control system have good self-evolution capability. The simulation results demonstrate that the fuzzy optimal method has certain validity and feasibility for error compensation of inertial elements in navigation system, it has better practical worth.
