一种用于直流电机的独立数字分数阶PID控制器及控制方法
摘要：
本发明公开了一种用于直流电机的独立数字分数阶PID控制器及控制方法，包括降压变换器，直流电机系统，分数阶PID控制器。其中降压变换器是一种静态功率电子电路，可将固定的直流输入电压转换为可变直流输出，由于使用电感器和电容器，DC/DC降压转换器产生平滑的直流输出电压和电流，波纹较小，噪声降低。直流电机由电枢和励磁绕组组成，直流电机由励磁电流和电枢电压激发。由于使用分数阶PID控制器，本发明可以提供更平稳的速度控制，而不需要额外的组件或电路。在非整数分数阶PID控制器用于整数系统的应用中，调整增益和相位特性比使用整数分数阶PID控制器时具有更大的灵活性。这种灵活性使得分数阶控制在设计鲁棒控制系统方面具有强大的优点。
摘要（英）：

The invention discloses an independent digital fractional order PID controller and a control method used for a DC motor. The independent digital fractional order PID controller comprises a buck converter, a DC motor system and a fractional order PID controller, wherein the buck converter is a static power electronic circuit that can convert a fixed DC input voltage into a variable direct current for output; due to the adoption of an inductor and a capacitor, the DC/DC buck converter generates smooth DC output voltage and current, the ripple is small and the noise is reduced; and the DC motor consists of an armature and an excitation winding, and the DC motor is excited by an excitation current and an armature voltage. By adopting the fractional order PID controller, more stable speed control can be provided without the need for additional components or circuits. In the application of a non-integer fractional order PID controller used in an integer system, the adjustment gain and phasefeatures have higher flexibility compared with that of an integer fractional order PID controller, and the flexibility enables fractional order control to have great advantages in designing a robust control system.
