“…In recent years, significant progress has been made in the study of the stability of nonlinear systems based on fuzzy control and adaptive control. For example, Wang et al [18] proposed a finite-time adaptive fuzzy eventtriggered control method for nonstrict feedback stochastic nonlinear systems with multiple constraints. This method achieves system stability within a finite time and offers good adaptability and robustness, making it particularly suitable for complex nonlinear systems.…”

“…Through dynamic surface control technology, it has been proven that the signal of the closed-loop system is semi-globally consistent and ultimately bounded, effectively avoiding Zeno behavior and emphasizing its stability and robustness. Wang et al [18] proposed a finite time adaptive fuzzy event-triggered control strategy for nonstrict feedback stochastic nonlinear systems. This strategy takes into account time-varying output constraints and input delays.…”

In order to meet the demands of autonomy and control optimization in solar greenhouse control systems, this paper developed an intelligent temperature and humidity control system for greenhouses based on the Single Neuron Proportional Integral Derivative (SNPID) algorithm. The system is centered around the Huada HC32F460 Micro-Controller Unit (MCU) and the RT-Thread operating system, integrated with the SNPID control algorithm. Through comprehensive simulation, model construction, and comparative experiments, this system was thoroughly evaluated in comparison with traditional PID control systems (cPID) that rely on overseas software and hardwsbuare. Simulation results show that our new system significantly outperforms traditional PID (Proportional Integral Derivative) systems in terms of temperature control stability and accuracy. Experimental data further confirm that, while ensuring cost-effectiveness, the new system achieves a remarkable 50.2% improvement in temperature and humidity control precision compared to traditional systems. The temperature Root Mean Square Error (RMSE) in the experimental greenhouse is 0.734 compared to 1.594 in the comparison greenhouse, indicating better stable temperature control capability. The vents in the experimental greenhouse have a maximum opening of 67 cm and a minimum of 5 cm, showing a quick response property to high temperatures. In contrast, the control greenhouse has a maximum vent opening of 55 cm, remaining unchanged during the test period, which reflects its slower response to temperature fluctuations. These results demonstrate the significant advantages of the designed solar greenhouse temperature and humidity control system in terms of autonomy and control optimization, providing an efficient and economical solution for solar greenhouse environmental management. This system shows significant practical application perspective in promoting intelligent agriculture and sustainable agricultural production, highlighting its broad impact and potential significance.
