The foreign research on the automation and intellectualization of the combined harvester has achieved abundant results. For example, Huisman, Voo Loo and Heijning judge the feeding amount by detecting the torque of an auger, control the operation speed, Kruse and Krutz control the operation speed by the load of an engine, Andersen describes that the operation speed is controlled by detecting the volume of harvested grains, and the Japanese Potention field PR0481-M type combined harvester adopts a rubber track and a semi-feeding type axial flow roller, and has the functions of automatic load display, automatic direction control, automatic feeding amount adjustment, automatic engine stop and automatic oil injection during overload and the like; the combine harvester of companies such as Netherlands, Diels and the like is provided with systems such as electronic information display, electronic driving control and the like, and the systems mainly control the conventional parameters of the combine harvester, such as the rotating speed of an engine, the pressure and temperature of engine oil, the quantity of fuel, voltage and the like, and also control the random working performance parameters, such as the actual running speed, the rotating speed of a power output shaft, the working area, the working efficiency, the working time and the like; the 'Field Star' system terminal of Massey Ferguson corporation in England has a very important system diagnosis function, once the system has a fault, a user can find the fault through a diagnosis tool, and therefore the fault is rapidly solved. In recent years, a great deal of research is done in China on the aspect of improving the automation and intelligence level of the combine harvester, certain achievements are obtained, and the gap between the combine harvester and the foreign advanced technology is shortened. For example, the feeding amount is detected by adopting the pressure of an inclined conveyor to a bottom plate in medium warfare and the like, and a threshing system simulation controller and a simulation control test bed taking a single chip microcomputer as a core are designed by establishing a grain motion mathematical model and a power consumption model in a threshing space. The yew bin utilizes the torque of a feeding driving shaft to detect the feeding amount in real time, designs a neural network controller to control the operation speed, detects the feeding amount by the oil pressure of a roller driving hydraulic system, predicts the walking speed by fuzzy control, and utilizes a PID algorithm to control the operation speed; a threshing cylinder and a speed monitoring system of each working shaft are developed by the university of eight agricultural reclamation in Heilongjiang; the university of Jiangsu develops a rotating speed alarm device of a rotating part of a combine harvester based on a Hall sensor and an 89C51 singlechip; a grain entrainment loss monitoring method and a grain entrainment loss monitoring sensor are provided by Jiangsu university, and a threshing cylinder rotating speed monitoring system of a combined harvester is developed by northwest agriculture and forestry science and technology university.
From the research on the automatic control of the combine harvester at home and abroad, the application of the advanced information technology and the intelligent control technology to the combine harvester is a necessary trend for the automatic control development of the combine harvester. The above research provides many ideas for the automatic control of the combine harvester, but there are also certain limitations: (1) the research objects are mainly focused on the load of the threshing cylinder, other working parameters are rarely considered, the research objects mostly belong to a control system with a single input control signal, and the defects of hysteresis or inaccurate parameter detection exist; (2) most of the research is in the experimental stage, and the actual automatic control system and the corresponding actuating mechanism are not developed to be applied to the combine harvester. Therefore, the high-performance multi-input multi-output combined harvester operation state self-adaptive control system is an important premise for ensuring the operation performance of the combined harvester.
