An automatic control system for a harvester was designed based on the integral separation PID control algorithm under the control of a single-chip microcomputer. With STC12C5A60S2 as the control core, the system collects corresponding data and information through the threshing drum rotation speed signal detection module, the grain feeding amount detection module, the threshing drum torque detection module, and the grain auger shaft rotation speed module. After being processed by the coordinated comprehensive algorithm inside the system, it outputs corresponding control signals to the electric push rod in real time, regulates its AD value to drive the action of the HST transmission, and then obtains the optimal integral separation limit beta value to control the harvester traveling system to reach the optimal state. It can also handle sudden situations such as overload speed reduction or locked rotor during the harvester's operation in real time. Finally, through simulation experiments, the comparison of the control effects between the traditional PID control algorithm and the integral separation PID control algorithm under three different integral separation limits was completed respectively. The results of the simulation experiments show that the optimal design of the mechanical control system based on the integral separation PID control algorithm must be based on the traditional PID control algorithm and appropriately adjusted with the optimal parameter proportion.

The rapid development of computer technology has promoted the research of complex network synchronization in network environments, which involves practical fields such as the Internet of Things, transportation networks, social networks, and biological systems. In this paper, the latest research and trends in limited bandwidth complex network synchronization control are surveyed. The following aspects are discussed regarding control methods for complex network synchronization and limited communication bandwidth: Firstly, by analyzing current research on complex network control, the methods of discontinuous control and finite-time control are discussed. Secondly, from the perspective of effectively utilizing communication bandwidth resources, synchronization control methods for complex networks with limited bandwidth are described. On the one hand, the studies on event-triggered synchronization control for complex networks are reviewed to reduce the volume of data transmissions. On the other hand, research on synchronization control in complex networks using quantification-based coding-decoding methods is explored to reduce the volume of transmitted data. In addition, considering the current security issues facing networks and systems, the ongoing research on secure synchronization control of complex networks under cyber-attacks is described. Lastly, some future directions for investigating the synchronization of complex networks with limited bandwidth are suggested.
