DESIGN OF SEMI-PHYSICAL SIMULATION PLATFORM FOR GRAIN CLEANING AND REGULATING SYSTEM

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.
