非最小相位连续时间系统广义预测加权控制算法

Continuous-time Generalized Predictive Weighted Control Algorithm for Non-minimum Phase Processes

针对连续时间广义预测控制(CGPC)算法,在λ=0以及Nu=Ny-ρ的特殊情况下不能保证对非最小相位系统的鲁棒性的问题,提出了加权预测控制算法,使非最小相位系统闭环设定点响应与B(s)无关.仿真结果表明了算法的有效性.

The continuous-time generalized predictive control(CGPC) law has some robustness for the special case when λ and Nu is respectively equal to 0 and Ny-ρ,even the system will be unstable for non-minimum phase processes under the limited condition.A new weighted predictive control algorithm is introduced and the dynamic characteristic of the closed-loop set-point response is irrelative to B(s).An illustrative example shows the performance of the application of the results presented.
