摘要:
针对具有不确定性的多输入多输出(MIMO)网络控制系统,提出了1种调度与控制协同设计方法。为改善网络服务质量(QoS),将死区调度策略应用于MIMO网络控制系统,并将该系统建模为一类具有不确定性和时延的离散线性系统。为补偿网络诱导时延的影响,构造了1种状态观测器和反馈控制器。基于Lyapunov函数法和锥补线性化方法,给出了系统渐近稳定的充分条件及控制器设计的迭代求解法。针对死区阈值的优化,提出了1种基于二分法的阈值优化迭代算法。仿真算例表明该文方法是有效的。
Abstract:
A novel scheduling and control co-design method for a multiple input multiple output(MIMO)networked control system with uncertainties is proposed here.A dead band scheduling strategy is applied to the MIMO networked control system to improve quality of service(QoS),and the control system is modeled as a discrete linear system with uncertainties and delay.An observer and feedback controller is proposed to deal with the network induced delay.The sufficient condition for asymptotically stable and a controller design iteration approach are delivered using the Lyapunov function and cone complement linearization.An iterative algorithm for threshold optimization based on the bisection method is given to optimize the dead band threshold.Numerical simulation results demonstrate the effectiveness of this method.
