Active Control of Large Telescopes: Active Optics,thermal gradients, and the changing gravity loads. The case of a monolithic mirror is considered first, followed by that of segmented mirrors (all telescopes with a primary mirror larger than 8 m will be segmented). The control strategy is based on a quasi-static model between the actuator inputs an

Semi-active Control,little energy). Next, the magneto-rheological (MR) fluids are described, and their modelling is briefly discussed (the simple Bingham model is sufficient in many applications); the operating modes (valve, shear, pinch modes) are described. It is followed by a discussion of various MR devices: MR sho
