A design method for PID controllers based on the direct synthesis approach and specification of the desired closed-loop transfer function for disturbances is proposed.Analytical expressions for PID controllers are derived for several common types of process models,including firstorder and second-order plus time delay models and an integrator plus time delay model.Although the controllers are designed for disturbance rejection,the set-point responses are usually satisfactory and can be tuned independently via a set-point weighting factor.Nine simulation examples demonstrate that the proposed design method results in very good control for a wide variety of processes including those with integrating and/or nonminimum phase characteristics.The simulations show that the proposed design method provides better disturbance rejection than the standard direct synthesis and internal model control methods when the controllers are tuned to have the same degree of robustness.
一种基于直接合成方法和所需的闭环传递函数扰动的PID控制器的设计规格为基础的方法.PID控制器的解析表达式推导过程模型,包括一阶和二阶加纯滞后模型和一个积分加纯滞后模型的几个常见的类型.虽然是抗扰控制器设计,设定点的反应通常是令人满意的,可通过调整设定点加权因子独立.九仿真实例表明,该设计非常好的各种各样的进程,包括与整合和/或非最小相位特性的控制方法的结果.仿真结果表明,所提出的设计方法提供了比标准的直接合成和内模控制的控制器时都调整到有同样程度的鲁棒性干扰抑制方法.
