用matlab进行仿真,出现错误了,怎么解决
An error occurred while running the simulation and the simulation was terminated
Derivative of state '1' in block 'PMWTGSM/Permanent Magnet Synchronous Machine/Electrical model/iq,id/iq/iq ' at time 0.70000000000000007 is not finite. The simulation will be stopped. 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)
出现上述错误,要怎么修改啊,小白一枚,求大大指导
