Combine harvesters are widely used in agricultural production. Keeping the palstance of combine threshing cylinder constant when the combine works normally has important implications, through which can improve the efficiency and guarantee the quality. In this paper the Foton Lovol GF40 combine is used as the controlled object, then a constant palstance control system is designed based on STM32, and the control program is also designed based on the fuzzy PID algorithm. The control system can receive the signals of feed quantity and cylinder palstance, then drive the HST system and change the walking speed according to the change of the signals received, thus to control the cylinder palstance. Field trials verify the feasibility of the system, show that the system has a certain stability, which can achieve the desired effect.

Fuzzy Adaptive

In previous work, the performance of PID plus an adaptive neural network compensator (ANNC) was compared with the performance of a novel fuzzy adaptive PID algorithm, as applied to position control of one axis of a pneumatic gantry robot. The fuzzy PID controller was found to be superior. In this paper, a simplified non-adaptive fuzzy algorithm was applied to the control of both axes of the robot. Individual step results are first shown to confirm the validity of the simplified fuzzy PID controller. The fuzzy controller is then applied to a sinuosoidal tracking problem with and without a fuzzy PD tracking algorithm. Initial results are considered to be very promising. Future work requires developing an adaptive version of the controller in order to demonstrate robustness relative to changing tracking frequencies and changing supply pressures.

Station Control System

This paper introduced a design and implementation of heat exchange station control system based on PLC and industrial configuration software, including the control scheme and principle, hardware selection and software design, etc. The circulating pumps and replenishing pumps in the system can all be driven automatically by PLC and inverter. Main process parameters e.g. steam pressure and measurement temperature can all be shown on the industrial PC running configuration software, and instructions could be sent by the engineer and operator on-the-spot via the Human Machine Interface as well. The automatic pressures adjustment of steam supply of the heater by advanced PID algorithm has been realized finally. It is verified that the system is highly reliable and stable, and it greatly enhances the level of automation and pressure control accuracy of the heat exchange station and meets all the equipments running demands well.
