This paper proposed new IMC-PID controller design method that use loop shaping method. It could consider such design specifications as gain margin, phase margin, sensitivity function etc by appling the loop shaping method for tuning IMC-PID controller whose structure has only one design parameter and guarantees internal stability. To shape desirable loop gain, the relation between these design specification and parameter is derived by mathematical basis. And the availability of proposed in this paper tuning method that can regard design specifications is checked through example comparison and analysis.

All artificial infernal organs which are using electric energy supply energy with inductive couple. Transcutaneous energy transmission system enhance survival chance of the patients and quality of life by reducing volume and mass. In this research, we used both tune in transmission system in state of fixing cycle in order to increase the voltage gain and the current gain and to reduce effect of leakage inductance. Also to maximize the effect of resonance, a constant frequency duty cycle control method is used. Test is progressed with litz wire which is set up with various sizes of core to minimize size of converter. This research aimed in analysis of transcutaneous energy transmission system and in measuring of stability and efficiency of Lithium-ion battery charge which are using transmitted energy.
