Introduction As one kind of the lightest engineering materials, magnesium alloys have a great potential for wide application in the automotive industry due to their high strength-to-gravity ratios[1].
The workpiece material used was the AZ31 magnesium alloy (composition (W/%): Al-3, Mn-0.2, Zn-1, Mg- Balance）.
If the exit temperature is kept varying in a certain range, not only product quality consistency but also productivity, material yield and die service life can be improved.

In order to satisfy stringent requirements for precision control and lightweight miniaturization, smart materials such as shape memory alloys, piezoceramics, electroorheological fluids and magnetorheological fluids are frequently adopted for controllable structures.
Piezoelectric materials can be effectively used for active vibration control with fast response and easy implementation [1- 3].
Mayhan combined intelligent control and smart materials to produce an adaptive and robust controller to dampen the fundamental vibration mode of the system in the presence of modeling uncertainties [7].
