摘要
对具有干扰的非线性系统，给出了一种线性化方法，通过状态反馈和干扰前馈变换，将非线性系统变换为等价的伪线性系统，给出了线性化的具体算法，并通过实例将非线性系统线性化．该法是不含干扰非线性系统反馈精确线性化方法的推广，具有更广泛的实用性．
Based on the notion of equivalence, the problem of transforming nonlinear systems with input disturbances to quasilinear systems is investigated. The transformation algorithm which consist of state space coordinates change and control input space coordinate change by nonlinear feedforward of the disturbances and feedback of the states is presented. An example for transforming the nonlinear system by using the algorithm suggested is also given.The method is the extension of exact feedback linearization for nonlinear systems without disturbances and has widespread reality.
