求助一个控制的SIMULINK 问题
我编制了一个LQR控制的SIMULINK程序。采用变步长积分运行没有问题,但采用定步长积分(fixstep)时运行总是出错跳出。提示信息
Derivative input 456 of 'lqr_semiactive_tj_three/output as x' at time 0.485 is Inf or NaN.Stopping simulation.There may be a singularity in the solution.If not, try reducing the step size (either by reducing the fixed step size or by tightening the error tolerances).
我修改了步长或是把步长调整为AUTO都不管用。请大家帮忙
因为需要做试验验证,所以必须用定步长积分来运行啊
谢谢大家了! try reducing the step size 试过了,多小都没用啊
