根据维生素C生产工艺的操作分析和对控制的要求,本文开发应用了隐式自校正广义预测控制算法和相应的程序,并针对过程的时滞特性,在性能指标中引入输出预测误差加权矩阵,较好地解决了该生产过程慢时变、大滞后的跟踪控制问题。 According to the operational analysis of vitamin C production process and the requirements of control, this paper develops and applies implicit self-tuning generalized predictive control algorithm and corresponding programs. In view of the time-delay characteristics of the process, the output prediction error weight matrix is ​​introduced into the performance index, It solves the problem of slow and time-varying, large-delay tracking control of the production process.
