你好,我的课题是一个simulink仿真问题;模型已经建好,在仿真时总是出现一些警告:Warning: Unable to reduce the step size without violating minimum step size of 0.001 at time 0.05386831471654953. Continuing simulation with the step size restricted to 0.001 and using an effective relative error tolerance of 29.05504001967259, which is greater than the specified relative error tolerance of 0.001.用的是变步长ode45法,请问:问题出现在那里?试着换了下算法,也没有解决问题!!
