为了解决温室条件下环境的非线性及时变、大时滞的缺点,试验提出基于LS_SVM的内模控制系统方法和算法,对温室环境系统控制进行了仿真试验。结果表明:基于LS_SVM建立的被控对象的内部模型和逆模型都具有非常高的精度和泛化能力,该控制系统在抗干扰能力方面和控制性能方面有非常不错的表现,同时具备较为良好的鲁棒性能。 In order to solve the nonlinear and time-varying and time-lag problems of the environment under the greenhouse conditions, this paper proposes a method and algorithm of internal model control system based on LS_SVM to simulate the control of greenhouse environmental system. The results show that both the internal model and the inverse model of the controlled object based on LS_SVM have very high precision and generalization ability. The control system has very good performance in terms of anti-interference ability and control performance, and has better Robust performance.
