    The essential role played by amplification and control in the successful development of the differential analyzer is described. This first occurred in 1930 with the introduction of the capstan torque amplifier in Vannevar Bush's largely mechanical form, and then in 1947 with the use of the voltage operational amplifier in an electronic embodiment that was called an electronic analog computer.

    Under the assumption of weak joint elasticity, a singular perturbation argument is used to show that recent adaptive control results for rigid robots can be used to control flexible-joint robots provided a simple correction term is added to the control law to damp out the elastic oscillations at the joints. In this way, fundamental properties of rigid robot dynamics can be exploited to design adap... View full abstract»
