For a class of switching motion control systems, optimal values of the switching parameters are obtained through a machine-in-the-loop optimization approach. The optimal parameters provide the means to balance servo performances. High-gain feedback is switched on to suppress large amplitude oscillations and is switched off to avoid amplification of small amplitude noises. Stability and servo performance are studied using a fast motion system which requires nanometer accuracy.

We test whether born-to-be-green represents a signal toward potential venture capital (VC) investors - on a sample of Italian, independent, unlisted, high-tech entrepreneurial firms. We employ several identification strategies by controlling for the major potential signals, and the alleged selection bias between green and non-green entrepreneurs. We exploit firm-level information about the “active searching for VC financing”. Alternatively, we exploit the cross-region variation in local government laws to foster green innovations in an Instrumental Variables setting. Our results show that running a green business per se is not correlated with the likelihood to receive VC, while the perception to run a green business is strongly and positively correlated with the likelihood to get VC. When investigating the contingencies associated to the effectiveness of the born-to-be-green signal – and the entrepreneurial ability to sell it – we find that only entrepreneurs who run a green business and perceive it as green are more likely to get VC funding.
