基于模糊PID控制的磁流变减振控制器
|
摘要
由于磁流变减振器的阻尼可控性具有非线性、回滞性和饱和特性,使其控制器的开发相对复杂。依据磁流变减振控制器的控制原理和设计功能,结合模糊PID控制算法,提出采用三闭环磁流变减振控制系统的设计思想,包括加速度环、电压环和电流环,保证控制系统的精度和实时性。详细介绍磁流变减振控制器的硬件电路设计和DSP控制系统的软件设计,并进行减振器的台架试验。试验结果表明,该磁流变减振控制器是正确的和可行的。
As the controllable damping property of MR damper has nonlinearity,hysteresis and saturation peculiarities,the development of its controller becomes quite complex.According to the control principle and design function of the MR damper controller,a three-loop controller is proposed based on the fuzzy PID algorithm,which includes an acceleration loop,a voltage loop and a current loop.The controller can effectively ensure the MR system precision and real-time.The hardware design of the MR damping controller and the software design of the DSP control system are introduced in detail,and the bench test is also implemented.The experimental result proves that the design of MR controller is correct and feasible.
