| 摘 要： | 针对暖通空调(HVAC)系统,提出一种基于粒子群优化(PSO)算法和最小二乘支持向量机(LSSVM)的预测控制方法。该方法利用LSSVM建立HVAC系统预测模型并预测系统的输出值,引入输出反馈和偏差校正以克服模型失配等因素引起的预测误差,以此构造加权预测控制性能指标。由PSO算法滚动优化得到系统的最优控制量。利用该控制方法对一个HVAC系统进行仿真实验,结果表明该方法具有较好的控制效果。

| Abstract: | For the system of heating,ventilating and air-conditioning(HVAC),a nonlinear predictive control algorithm based on particle swarm optimization(PSO) and least square support vector machine(LSSVM) was proposed.It utilizes LSSVM to estimate the HVAC system model and forecast the output value,reducing the error in output feedback and error correction.A new weighted predictive control performance index is formulated.The optimal control values of the nonlinear system are obtained by the rolling optimization of PSO algorithm.An optimal control system is designed to control a HVAC system;simulation results show that the proposed nonlinear predictive control algorithm is effective. |
