Both the controlled object and the reference model are controllable and observable. 2. Nj 0. 3. Zeros of C zE - A -1 B are stable. 4. f v k a 11 v k Y a 0 p 0 0 Y 1 . 5. 6. Existing condition of v k is I Cv2 Bs2 df v k dvT k 0. zE - A 0 and rankE deg zE - A r n . 5. Numerical simulation An example is given as follows 1 0 1 r0 1 01 0 01 r 0 1 1 x k 1 0 0 1 x k 1 0 w k 0 f v k 1 d k 1 0 1 _0 1J _1J v k 1 1 1 x k r 0 0 1 s 1 y k x k y 0 _1 57 f v k 3v3 k 4v k 1 1 v4 k Reference model is given by xm k 1 0 1 x k 0 m _1_ rm k Vm k 1 0 Xm k 58 rm k sin kn 16 . In this example disturbances d k and d0 k are ramp and step disturbances respectively. Then d k and d0 k are given as d k k - 85 85 k 100 d0 k 20 k 50 59 We show a result of simulation in Fig. 1. It can be concluded that the output signal follows the reference even if disturbances exit in the system. 6. Conclusion In the responses Fig. 1 of the discrete time model following control system for nonlinear descriptor system the output signal follows the references even though disturbances exit in the system. The effectiveness of this method has thus been verified. The future topic is that the case of nonlinear system for Y 1 will be proved and analysed. 140 Discrete Time Systems Fig. 1.
