双时间尺度温室环境最优控制仿真验证
A simulation validation for two-time-scale optimal control of greenhouse climate
摘要
Abstract
To address the problem of control performance degradation caused by long-term weather prediction errors in optimal control of greenhouse climate,a control objective model that represents the profit obtained in the control process was established based on lettuce and energy-related market prices in Beijing.Beijing's annual weather data,collected from the weather station,were used as the reference for long-term weather predictions.Three methods,including Gaussian white noise,time series reversal,and time substitution,were used to generate weather prediction errors.These transformed weather data were then used as real weather data for simulations.A greenhouse-lettuce mechanistic model was taken as the system model for simulations.The control performance was analyzed for the two-time-scale decomposed Receding Horizon Optimal Control(RHOC).Its yield,cost,and profit were compared with those from the traditional Model Predictive Control(MPC).The results showed that:MPC exhibited superior performance only under perfect weather predictions,whereas RHOC improved the profit by 1.24%,20.59%,and 21.32%respectively compared to MPC in scenarios with Gaussian white noise,time series reversal,and time substitution.The quantitative analysis in this study confirmed the superiority of the two-time-scale optimal control of greenhouse climate,and provided data support for the online implementation of control algorithms.关键词
