allan 方差（阿伦方差）是David AIlan于1966年提出的，最初该方法是用于分析振荡器的相位和频率不稳定性，高稳定度振荡器的频率稳定度的时域表征目前均采用Allan方差。由于陀螺等惯性传感器本身也具有振荡器的特征，因此该方法随后被广泛应用于各种惯性传感器的随机误差辨识中。(Allan variance (Allen variance) was proposed by David Allan in 1966. Initially this method was used to analyze the phase and frequency instability of oscillators. The time-domain characterization of the frequency stability of high-stability oscillators is currently based on Allan variance. Since gyros and other inertial sensors also have the characteristics of oscillators, the method is subsequently widely used in the random error identification of various inertial sensors.)

粒子群算法，也称粒子群优化算法或鸟群觅食算法（Particle Swarm Optimization），缩写为 PSO， 是由J. Kennedy和R. C. Eberhart等开发的一种新的进化算法(Evolutionary Algorithm - EA)。PSO 算法属于进化算法的一种，和模拟退火算法相似，它也是从随机解出发，通过迭代寻找最优解，它也是通过适应度来评价解的品质，但它比遗传算法规则更为简单，它没有遗传算法的“交叉”(Crossover) 和“变异”(Mutation) 操作，它通过追随当前搜索到的最优值来寻找全局最优。这种算法以其实现容易、精度高、收敛快等优点引起了学术界的重视，并且在解决实际问题中展示了其优越性。粒子群算法是一种并行算法(Particle Swarm Optimization (PSO), also known as Particle Swarm Optimization (PSO), is a new evolutionary algorithm developed by J. Kennedy and R. C. Eberhart. PSO is a kind of evolutionary algorithm, which is similar to simulated annealing algorithm. It starts from random solution and searches for the best solution by iteration. It also evaluates the quality of solution by fitness. But it is simpler than genetic algorithm rules. It has no Crossover and Mutation operation of genetic algorithm. As a result, it searches for global optimum by following the optimal value currently searched. This algorithm has attracted the attention of academia for its advantages of easy implementation, high accuracy and fast convergence, and has shown its superiority in solving practical problems. Particle swarm optimization is a parallel algorithm)
