Firstly , the equilibrium solution is global asymptotic stability and exponential stability on l2 [ 0 , l ] under neumann and dirichlet boundary control conditions , control inputs for choosing the boundary control is bounded in lx , the equilibrium solutions decay to zero and integrating the solution square in [ 0 , 1 ] , it decays to zero exponentially , by using nonlinear boundary control conditions and input feedback control method 首先,采用非线性边界条件输入反馈控制方法,研究得到该类方程在neumann和dirichlet边界控制条件下的平衡解在l _ 2 [ 0 , 1 ]上是全局渐近稳定和指数稳定的、在所选边界控制下控制输入是l _有界的、平衡解随时间衰减到零以及平衡解的平方在[ 0 , 1 ]上的积分按指数方式衰减到零。
The model control input information according as output information measure up ( related faction ) . matter - element transformation which made contradiction problem convert resolved problem exploit relevant strategy set . it make use of the strategy to solve existence problem in production controlling , thereby operating variable convert measure from fail field 该模型以控制输出信息的合格度(关联度)作为确定控制输入矫正量的依据,利用物元的可拓性,通过物元变换化矛盾问题为相容问题,从而开拓出有关的策略集,解决生产控制中存在的问题,使被控变量从不合格范围转化到合格范围内。
