摘　　要：联合收割机负荷模型存在严重的非线性和参数不确定性,在负荷控制器及其控制算法的研究中需要进行大量的试验,而负荷控制器的田间实车试验存在很多制约因素,难以实现全面试验。针对上述问题,建立了由负荷反馈控制器和虚拟联合收割机对象组成的半实物仿真试验平台。基于4LZ-2.0型全喂入收割机,设计了虚拟收割机模型和相应的各种工况,为研究开发联合收割机负荷反馈控制器及其控制算法提供有效的验证环境。最后,利用此平台模拟联合收割机实际作业过程,对负荷反馈控制器进行各种工况条件下的测试,试验结果表明了仿真平台的有效性。The combine is a serious non-linear system,and there are many uncertain parameters. Therefore the researches in the combine＇s load control need a lot of tests. Because of many constraints in the field tests,the comprehensive tests are elusive. In order to address these problems,a hardware-in-loop simulation platform was designed in this paper. The platform was formed by the load feedback controller and the virtual plant based on 4LZ2.0 combine. A test conditions designer was also provided. The system can be an effective tool for test the load feedback controller in research. Finally,a load feedback controller was tested on the platform under various test conditions. The result shows that the platform is useful.
