求教SIMULINK仿真错误：The diagram must contain a powergui block.The block must be named

求教SIMULINK仿真错误：The diagram must contain a powergui block.The block must be named simulink仿真中出现下面的错误,啥意思? 用simulink进行仿真时,出现错误,simulink中sum出错,Algebraic state in algebraic loop containing 'Lxsvpwm/Subsystem2/Sum2' computed at time 0.0 is Inf or NaN.There may be a singularity in the solution.If the model is correct,try reducing the 我在用simulink仿真时提示有两个错误,您可以看下么?Error using ==> rtwgenAlgebraic loops are not supported in generated code.Use the 'ashow' command in the Simulink Debugger to see the algebraic loops.Error building Real-Time Workshop 用simulink里的带通滤波器仿真出现的问题,总提示如下错误,可是不知道错误改怎么改,错误的提示：The sample time of the input signal and the sample time specified in the dialog box must be the same,The sample time of th simulink仿真中的问题我在用MATLAB中的SIMULINK做仿真时出现以下错误提示,Trouble solving algebraic loop containing 'chap5_1sim/TmpHiddenBuffer_Feeding_S-Function_AtInput1' at time 3400.
