A servo control loop for a disc player initially sets an offset value, which is used throughout search and playback to control the gain of an equalizer in the servo loop. The offset value is determined by first moving a pickup head to radially central position of the disc and reading ...

Loop-shaping H ∞ control with normalized coprime factorization is applied to a servo motor-driven precision positioning system. A high-gain controller is designed to attenuate the position errors caused by friction. The analysis of the controller shows that no limit cycle is introduced by the pres...
Peak closed-loop gain < 4 dB Discretization of Model Since the servo controller is digital, you can perform the design in the discrete domain. To this effect, discretize the HDA model using C2D and the zero-order hold (ZOH) method: Get Ts = 7e-5; Gd = c2d(G,Ts); bp = bodeplot...
