针对控制领域现有教学实验系统的不足,设计了基于FPGA平台的仿真与控制一体化实验系统,给出了系统结构、硬件电路及应用软件的设计。实验系统将控制器设计过程中的仿真环节与实际控制环节相结合,在Matlab/Simulink环境中结合DSP Builder技术进行控制系统的建模与控制仿真,直接生成可硬件实现的代码文件以完成实验验证,并通过上位机应用软件监测被控对象在不同控制参数下的响应特性。实验结果验证了所开发实验系统的有效性。
In view of the deficiency of existing teaching experiment system in the control field, an integrated experiment system of simulation and control based on FPGA platform is designed. The system structure, hardware circuit and application software design are given. The experimental system combines the simulation and the actual control in the process of controller design. The simulation and simulation of the control system in Matlab / Simulink environment are combined with DSP Builder technology to directly generate the code file that can be implemented in hardware to complete the experimental verification , And through the host computer application software to monitor the controlled object under different control parameters of the response characteristics. Experimental results verify the effectiveness of the developed experimental system.
