本文研究具有间断非线性项的Hammerstein系统的递推参数辨识问题，具有死区和预载荷的两段分段线性。一种特殊形式的Hammerstein模型与这种类型的非线性被纳入到递归最小二乘识别计划补充模型内部变量的估计。最后通过实例说明了该方法的有效性。
This note deals with the recursive parameter identification of Hammerstein systems with discontinuous nonlinearities, i.e., two-segment piecewise-linear with dead-zones and preloads. A special form of the Hammerstein model with this type of nonlinearity is incorporated into the recursive least squares identification scheme supplemented with the estimation of model internal variables. The proposed method is illustrated by examples.
