Implementation of Dynamic Matrix Control on Field Programmable Gate Array
2011年
High performance computer is often required by model predictive control(MPC) systems due to the heavy online computation burden.To extend MPC to more application cases with low-cost computation facilities, the implementation of MPC controller on field programmable gate array(FPGA) system is studied.For the dynamic matrix control(DMC) algorithm,the main design idea and the implemental strategy of DMC controller are introduced based on a FPGA’s embedded system.The performance tests show that both the computation efficiency and the accuracy of the proposed controller can be satisfied due to the parallel computing capability of FPGA.

基于混合H_2/H_∞的鲁棒预测控制综合设计方法被引量:8
2010年
针对具有有界扰动的多胞不确定约束系统,基于混合H_2/H_∞指标,提出一种鲁棒预测控制器设计方法.该控制器在保证系统对外界扰动的抑制指标前提下,具有较好的控制性能.同时,考虑了该控制器的可行性设计问题,通过附加约束保证了预测控制器的递归可行性.

酒精发酵系统的鲁棒预测控制器设计被引量:1
2010年
针对具有系统状态测量延迟和输入输出约束的酒精发酵系统,研究了其鲁棒预测控制器的设计问题。介绍了酒精连续发酵过程及其数学模型,通过在平衡工作点附近的线性化处理得到系统的线性化模型;考虑到发酵系统线性化模型的参数变化,采用多胞结构来描述发酵过程。以此为基础,借助LMI(Linear Matrix Inequality)工具将鲁棒预测控制器的在线优化问题转化为求解一组由线性矩阵不等式构成的优化问题。另外,针对系统部分状态的实时不可测性,通过二次规划求解进行状态估计,利用估算值为优化计算提供有效信息,解决了系统状态测量时延给预测控制器处理带来的困难。仿真结果证明了该方法的有效性。

An Improved Robust Model Predictive Control Approach to Systems with Linear Fractional Transformation Perturbations被引量:2
2011年
In this paper, a robust model predictive control approach is proposed for a class of uncertain systems with time-varying, linear fractional transformation perturbations. By adopting a sequence of feedback control laws instead of a single one, the control performance can be improved and the region of attraction can be enlarged compared with the existing model predictive control (MPC) approaches. Moreover, a synthesis approach of MPC is developed to achieve high performance with lower on-line computational burden. The effectiveness of the proposed approach is verified by simulation examples.
