基于WSN的温室温度分布式事件触发控制系统研究
Research on distributed event-triggered control system based on WSN for greenhouse temperature
摘要
Abstract
In greenhouse temperature control system,since communication bandwidth and node resources in wireless sensor network(WSN)are constrained,a distributed event⁃triggered control scheme is proposed. In the scheme,each sensor node in combination with its own information transmits state sampling values only when system has control requirements,which saves sys⁃tem resources effectively. Particle swarm optimization(PSO)based on chaos variation was adopted to calculate optimum control quantity,which is simple and can improve premature convergence. Simulation results show that data transmission rate of sensor nodes is reduced greatly under distributed event⁃triggered control mechanism,but system still achieves satisfied control effect.关键词
