考虑如下模型: {xi(k+1)=xi(k)expri(k)-ai(k)xi(k)-∑nj=1aij(k)∑∞s=0Kij(s)xj(k-s)-bi(k)∑∞s=0Hi(s)ui(k-s)Δui(k)=-ci(k)ui(k)+di(k)∑∞s=0Ri(s)xi(k-s)(i=1,2,…,n)的全局吸引性问题,通过构造适当的Lyapunov函数得到该系统全局吸引的充分性条件.
The global attractivity of the following model is considered {xi(k+1)=xi(k)expri(k)-ai(k)xi(k)-∑nj=1aij(k)∑∞s=0Kij(s)xj(k-s)-bi(k)∑∞s=0Hi(s)ui(k-s)Δui(k)=-ci(k)ui(k)+di(k)∑∞s=0Ri(s)xi(k-s)(i=1,2,…,n)By constructing suitable Lyapunov functionals,sufficient conditions are obtained for the global attractivity of the above system,which complement the results of the paper.
