【摘要】 PID控制是过程控制中应用最为广泛的一种控制方法,分数阶mlDPI控制是常规的整数阶PID控制的推广与发展。本文对通过在复平面映射后的根轨迹对分数阶mlDPI控制器的控制特性、参数的整定等进行了研究,研究表明mlDPI控制器控制参数和阶次的改变都能改变控制质量,而且控制器对其本身参数和系统参数的变化并不敏感,mlDPI控制器具有更灵活的结构和更强的鲁棒性。更多还原

【Abstract】 PID control is the most common control method used in process control. Fractional-order mlDPI control is the generalization and development of the integer-order PID control. In this paper, the control properties and parameters tuning of the fractional-order mlDPI controller are investigated by using the mapping root locus. The simulation results show that fractional-order controller is not sensitive to the changes of control parameters and system parameters. It has flexible structure and stronger robustness.更多还原
