WebIV describes the SINDy’s extension with external measurements; Section V shows the steps and convergence details of SINDy algorithm; the proposed algorithm is applied to a SG example in Section VI; Section VII presents conclusions. The Appendix contains basic SG’s parameters adapted for SINDy-based model identification. WebSINDy with control algorithm is illustrated in ﬁgure2on a disease model used in the next section. To evaluate Q, we ﬁrst measure m snapshots of the state x and the input signal
