| 英文摘要 |
| A desired model of ITAE(integral time absolute error) optimal time-delay system is presented based on the canonical form of ITAE optimal system(ITAE–OS). By making use of Maclaurin expansion, a design method for ITAE suboptimal time-delay system(ITAE–STDS) is discussed. The comparison of the third order ITAE–STDS with ITAE–OS reveals their similar dynamic performance in requency domain and time domain. Case studies in design of PID and the lead-lag compensator are given. Comparisons of step response, load rejection and parameter robustness show that the resulting systems have satisfactory performance by using the proposed method. |
