- •
EDM process is in nonlinear stochastic dynamics, easily into unstable process.
- •
Severe electrode fluctuations occur when adopting adaptive minimum variance strategy.
- •
A coupled control strategy is proposed considering both machining rate and stability.
- •
Experiments confirm the superior performances of the new coupled control strategy.
- •
The newly developed control system has been proved working well in severe conditions.
