摘要
针对传统幅值最优及其抗干扰技术存在的问题,基于新的幅值最优模型,提出了PI求解方案。与传统的幅值最优及抗干扰PI整定公式相比,新的PI整定公式,减少了所需特征参数的个数,新的抗干扰幅值最优PI整定公式也大大简化。改进后的幅值最优求解方法,扩大了幅值最优技术的应用范围;改进后的抗干扰设计比原有方法有更好的抗干扰性能。通过被控对象的仿真比较实验,证明了改进方法的有效性。
The new design method of PI controller based on magnitude optimum criterion is presented to solve the problem of traditional magnitude optimum and its design tbr improving disturbance rejection. Compared with traditional tuning formula, the new PI tbrmula needs less characteristic parameters and is simplified for improving disturbance rejection which expands the applications of magnitude optimum technique with the better pertbrmance. The simulation results show that the method and its design are effective.
