摘要:
建立了液压伺服系统的数学模型,并进行控制系统软、硬件的设计,采用 32 位 STM32F103ZET6 和 TMS320F28335 双核心处理器,通过 SPI 通信分工协作,充分利用了单片机的控制优势和 DSP 的数据处理功能进行高精度电液伺服控制。另外,设计了完善的系统故障自检测报警程序与复合控制算法程序,在提高了系统稳定性与智能化的同时,又提高了整个系统的精度。 针对电液位置伺服系统的不确定性、非线性和常规控制的缺点,设计了具有在线参数调整的模糊自整定控制器,将模糊控制与 PID 控制相结合,根据电液伺服系统参数的实时变化,自动调整 PID 控制的参数,以减小电液位置伺服系统中参数摄动等引起的超调和振荡。 通过 Matlab 仿真比较,模糊 PID 控制器比传统的 PID 控制器能达到更好的控制效果。
Abstract:
A mathematical model of the hydraulic servo system is established and the software and hardware of the control system are designed. With dual - core processor with 32 - bit STM32F103ZET6 and TMS320F28335, the data communication between STM32F103ZET6 and TMS320F28335 is realized by SPI,which makes full use of the control advantages of single-chip microcomputer and DSP data processing function for high-precision electro-hydraulic servo control. The perfect self-diagnosis alarm program for system failure and the complex control algorithm program are designed,which not only improve the stability and intelligence of the system,but also enhance the precision of the whole system. Aiming at uncertainty,nonlinear of the electro-hydraulic position servo system and the shortcomings of conventional PID control,a fuzzy self-tuning PID controller is designed to reduce the overshoot and oscillation caused by the electro-hydraulic position servo system爷s perturbation. The simulation indicates that the fuzzy PID controller gives a better control performance than PID controller.
