ads优化时current EF得不了0，怎么办？

仿真结果如下
Iteration/Trial #0:
CurrentEF: 2499.99999991314
Optimization variables:
TL2.L = 22.2767e-03
TL1.L = 22.2767e-03
Nominal Optimization found no improvement in performance.
The initial solution may be an optimal solution under the constraints.
Possible remedies include:
- Try a different optimization method. Perhaps Random first,
Gradient second.
- Check to insure optimization variables are sensitive to goals.
- Relax the specification, later re-tightening.
- For Random-type optimizers, increase the number of trials.
- If the simulation fails to converge for Random-type optimizers,
try using a Gradient method.
- Check that the Error Function "EF" is not initially zero.
If it is, you may tighten the specification.
Optim1[1] reached the iteration limit.

前面那个那个s-parament是我开始弄错了用log扫描留下的

 

2499也差太远了吧，结构原理有问题吧，要不就是你设错了

 

优化方式你就选那个 Gradient，应该很快就能收敛了
