| 摘 要： | 研究具有非整数倍采样周期时延的网络控制系统(NCS)的时延补偿问题.针对NCS中的非整数倍采样周期时延,基于广义预测控制算法并结合线性插值方法,提出一种新的网络时延补偿方法.该方法能得到非整数倍采样周期的控制预测值,同时通过减小执行器读取缓冲区的周期,可有效减少由于执行器时间驱动而引起的等待时延,解决了非整数倍采样周期时延的补偿问题.最后通过仿真验证了该方法的有效性.

| Abstract: | The delay compensation problem is investigated for networked control sysetm(NCS) with delay of non-integral multiple of sampling period.A new delay compensation approach is proposed based on the state-space-based generalized predictive control(GPC) strategy and the linear interpolation method.The control sequences of non-integral multiples of sampling period can be derived by using the newly proposed approach.Moreover,the waiting delay is efficiently reduced by decreasing the actuator's reading period.Final... |
