A 1.14, T. = Seven seventy-one seconds under the curve of the transition process, the 1ATE a 1.2731 × 10. This shows the best performance of control system control. 3.1.2 steam flow disturbances in the steam flow control performance comparison unit step disturbance at the Canadian Figure 5 Head {s get the best parameters as shown in Figure 5, the transition curves,[link widoczny dla zalogowanych], where curve 1 is the traditional PI control system curve of the transition process, the 1ATE: 1.2355 × 1O; curve 2 [1], the control system of the transition curves, the IA7, E = 4.2971 × 10; curve 3 for this transition process control system curve, A D E A 5.7814 × 1 \disturbance, the optimum parameters are shown in Figure 6, the transition process under the curve, which curve 1 is the conventional P1 control curve of the transition process,[link widoczny dla zalogowanych], which, I4 D E = 9.47:43 ×】 0; Curve 2 for the text 1] The curve of the transition process control system, the IATE a 7.344lx10; curve 3 for the present control system 456 * Thermal Power Engineering,[link widoczny dla zalogowanych], 1998, the transition curves in Figure 6, the D E: 7.1357X10. visible disturbance in the feed water flow under the control of this system still has the text of E13 as a good control performance. 3.2 Water Supply 3.2.1 Parameter instability in the load of the object model and the actual water flow to enhance the case of smaller, earlier identified by the application of good parameters. will this control system (Figure 3) Head 7, asked (s'100-10 Figure 8 time fs), 1 one hundred eleven 15001ooo Figure 95oo20o0 pm (;) model parameters in the water supply reduced by 20% D , the transition curves obtained in the curve in Figure 7】, the m D E A 3.6129) <10; increased by 20% to 71 parameters to obtain the transition curves in Figure 7, curve 2, the IATE-2 .7081 X10; the parameters reduced by 10%, the transition curves obtained in Figure 8, curve 1, the 71E = 1.1841 × 10; 10% of the parameter r increases, the transition curves obtained in Figure 8, Curve 2 its J71E a 5.3408 × 10; 10% reduction of the parameter K, the transition curves obtained in Figure 9, curve 1, the, D E = 1.5156 × 10. the parameters increased by 10%. be the transition curves in Figure 9, curve 2, the = 57031X10. can be seen; this control system model parameters on the water has strong robustness. 3.2.2 disturbance model steam load increase in the actual water flow smaller cases. applied to determine the optimal parameters in front, will this control system (Figure 3) in the steam parameters of the small perturbation model. decreased 40%, the transition curves obtained in Figure 10 curve 1, the 71 = 2.1833 × 10i100-1050o10o0IS002000 time () Figure 10 Figure 11 plants when you hear a 2 fs) Figure 12 (to 401)
