The ISA has a twofold task: starting-up the engine and generating electrical energy to be stored into a battery. This paper is focused on the first task. Two different motor are taken into account: an external rotor SPM machine and an IPM machine. For the control drive both the rotor configuration require the knowledge of their rotor position, then a sensorless technique based on the high frequency voltage injection for rotor position detection has been implemented. In order to create a high frequency anisotropy in the SPM rotor configuration, a ringed- pole solution has been adopted. Experimental tests have highlighted that the first machine has a good performance starting up the engine with a good speed and position estimation in spite of the particular no constant load. As regard the IPM machine, with this machine the sensorless engine start-up is not possible because at high current the anisotropy disappear a cause of saturation effects.

Micro-CHP (or nano-CHP depending on power level) is an energy-efficient technology that simultaneously provides heat and electricity to households. In this paper, the preliminary design of control and electric drive of a nano-CHP system is presented. The apparatus is under development in the frame of a national industrial research program INDUSTRIA 2015 (PIACE project) devoted to the design of an intelligent cogeneration system integrated with renewable energy sources. Simulation studies predict system performance, that has been validated by experimental test carried out on a dedicated laboratory test bench.

Nano-CHP is a growing technology that simultaneously provides heat and electricity to households. An Electric Machine (EM) connected to an Internal Combustion Engine (ICE) is used to produce the electricity, while ICE delivers heat. Any conventional ICE exhibits a pulsating torque which causes vibration and noise of the system and also reduces the power train life time. The additional task for the electric drive of smoothing the speed oscillations by controlling the EM as an active torque damping system, that applies an inverse torque sequence to crankshaft, is here proposed.

For this application the electric machine should exhibit a high torque during the engine start-up and a wide constant-power speed range during electric energy generation. Peculiarities of the synchronous reluctance machine are the possibility of a large torque overload at low speed, its extended flux-weakening capability, and its inherent fault-tolerance. In details, this paper reports the design of the electric machine, the results of finite-element computations, the description of the control system, and the experimental test measurements on the drive prototype.

Thanks to the proposed strategy the self-sensing capability of the machine can be evaluated during the design process. A small-signal model of the machine in the d-q reference frame is derived and adopted to perform suitable finite-element (FE) simulation to compute the machine parameters at the injection frequency. The proposed procedure is validated by the comparison with other simulation strategies as well as with experimental results.
