摘　　要：针对一类非线性连续系统的参数辨识问题，应用方块脉冲函数（ＢＰＦ）逼近技术．提出了一种参数递推估计算法．数字仿真结果表明了本文算法的有效性．This paper presents a parameter identification method for a nonlinear continuous-time system based on block-pulse function (BPF) approximation technique. First, the differential equation of the system is transformed to matrix algebraic equation via the BPF expansion procedure; second, the recursive algorithms are derived by using the properties of operational matrices of the BPF; finally, simulation example demonstrates the effectiveness and high identification accuracy of the presented algorithm.
