Abstract

To address the lengthy development cycle of grain air-screen cleaning devices, a semi-physical simulation platform for the grain cleaning regulation system was designed. The platform simulated actual operations, conducting open-loop and closed-loop tests with comparative analysis. Open-loop test results showed a speed error expectation of 0.8387 rpm and a fish-scale sieve opening error expectation of -0.0117 mm, while closed-loop tests yielded a speed error expectation of 0.679 rpm. Results confirmed the platform's ability to replicate actual conditions and validate the TC377 controller’s effectiveness, enhancing development efficiency.

针对谷物风筛式清选装置开发周期长的问题，设计出一套谷物清选调控系统半实物仿真平台。利用半实物仿真平台模拟实际作业过程，进行开环与闭环测试，与实际测试进行对比。其中，开环测试转速误差数学期望为0.8387rpm，鱼鳞筛开度误差数学期望为-0.0117mm，闭环测试转速误差数学期望为0.679rpm，试验结果表明了该仿真平台能够模拟谷物清选装置的实际工况以及TC377作为控制器控制算法的有效性，能够提高开发效率。
