摘要

针对一阶加死时间过程，给出了分数阶PI控制器的整定规则。在最大灵敏度的约束下，以最小积分绝对误差(IAE)为目标，建立了抗负载干扰的调谐规则。将PI控制器的分数阶项λ分别取为0.9、1.1和1.2，利用遗传算法最小化FOPDT系统的IAE，得到PI控制器的参数。最后，以ms为单位设计了调谐规则，并通过文献中的各种实例验证了所提方法的有效性。

Design of Fractional Order Pi Controller for First Order Plus Dead Time Process Based on Maximum Sensitivity

In this paper set of tuning rules for fractional order PI controllers has been presented for first order plus dead time process (FOPDT). The tuning rules have been developed by minimizing the integrated absolute error (IAE) for load disturbance rejection with a constraint on the maximum sensitivity eMs). The fractional order term of the PI controller λ has been taken as 0.9, 1.1 and 1.2 and parameters of PI controller has been obtained by minimizing IAE for FOPDT system by using genetic algorithm. Finally, the tuning rule is devised in terms of Ms. The effectiveness of proposed method has been verified by various examples taken from literature.
