基于FPGA的模糊PID控制在智能化温室中的仿真研究

采用VHDL语言编程,以FPGA为硬件载体、Quartus II软件为开发工具,采用自上而下的模块化设计思想,将模糊PID控制根据功能进行模块划分、模块设计,并利用软件自带的仿真功能对设计进行功能仿真和时序仿真。该控制算法的FPGA实现提高了控制的可靠性,加强了模块的通用性,减少了系统硬件开发周期,降低了设计开发成本。在智能化温室中采用基于FPGA的模糊PID控制可以提高控制系统的稳定性和可靠性。

THE STUDY ON THE SIMULATION OF FUZZY PID CONTROL BASED ON FPGA IN THE INTELLIGENT GREENHOUSE

Fuzzy PID control has many advantages, such as a small amount of overshoot and the short dynamic process, higher system stability, etc. The program is finished by the VHDL language, whose hardware is FPGA, development tool is Quartus Ⅱ. According to the function and timing simulation is completed by the built-in simulation function of the software, we adopt the design idea of the top-down modular and the module division in the design of the fuzzy PID control. The FPGA implementation of the control algorithm improves the reliability of the control, strengthens the commonality of the module, reduces the hardware development cycle of the system, and reduces the cost of design and development. The application of the fuzzy PID control Based on FPGA can improve the stability and reliability of the control system in the intelligent greenhouse.
