simulink仿真不确定性模型，主要学习第二个程序。
mdl = "rctUncertainModel";open_system(mdl)m = 3;c = ureal('c',1,'Percentage',20);k = ureal('k',2,'Percentage',30);usys = tf(1,[m c k])ublk = strcat(mdl,"/Uncertain State Space"); % 水平串联字符串set_param(ublk,"USystem","usys"); % 为mdl 设置不确定系统sim(mdl); % 标称模型阶跃响应%samps = struct('c',1.2,'k',1.7); % 某个不确定参数set_param(ublk,"UValue","samps"); % 设置不确定参数sim(mdl);%uvars = ufind(mdl); % 不确定参数结构体set_param(ublk,"UValue","usample(uvars)"); % 设置不确定参数随机采样sim(mdl);for i=1:5 % 随机绘制不确定参数的响应sim(mdl);end
