fuzzy Controller Design for synchronous motion in a dual cylinder electro hydraulic system
Control Engineering Practice, 2008Co-Authors: Chengyi Chen, Chicheng Cheng, George T C ChiuAbstract:Abstract In this paper, an integrated fuzzy Controller is proposed to achieve a synchronous positioning objective for a dual-cylinder electro-hydraulic lifting system with unbalanced loadings, system uncertainties, and disturbances. The control system consists of one-fuzzy coordination Controller for both cylinders and an individual cylinder Controller, comprised of a feedforward Controller, and a fuzzy tracking Controller, for each of the hydraulic cylinders. In the integrated fuzzy Controller Design, the fuzzy coordination Controller is responsible for dispatching motion synchronization commands to the individual cylinder Controllers. Each cylinder Controller then adaptively enforces the position tracking to its controlled actuator. The experimental results show that the proposed integrated fuzzy Controller Design can effectively achieve the objective of position synchronization in the dual-cylinder electro-hydraulic system, with maximum synchronization error within ±4 mm.

robust track following Controller Design for hard disk drives with irregular sampling
IEEE Transactions on Magnetics, 2013Co-Authors: Behrooz Shahsavari, Richard Conway, Ehsan Keikha, Fu Zhang, Roberto HorowitzAbstract:This paper considers robust Controller Design for track-following in hard disk drives (HDD) with irregular sampling of the position error signal (PES) but regular (clock-driven) control updates. This sampling and actuation behavior is modeled by applying a novel discretization method to a continuous-time model of an HDD, resulting in a discrete-time linear periodically time-varying model. Then, the Controller Design is performed using optimal H∞ control for periodic systems and uses a generalization of the disk margin to quantify the robustness of the closed-loop system. To show the effectiveness of the proposed method, the Design methodology is applied to a hard disk drive model and the resulting Controller is validated by examining its nominal performance in terms of the root mean square of the standard deviation of the PES and robustness in terms of disk margin. Since the proposed Controller has too many parameters to be implementable on an HDD due to memory limitations, we use a vector quantization method to approximate the entire parameter set of the Designed Controller by a smaller set of parameters.

track following Controller Design of mems based dual stage servos in magnetic hard disk drives
International Conference on Robotics and Automation, 2000Co-Authors: Roberto HorowitzAbstract:A decoupled Controller architecture and discrete time pole placement Design methodology is proposed for dual-stage servo Controller Design of magnetic hard disk drives. The methodology was applied to the Controller Design of a dual-stage servo with a MEMS microactuator (MA) which rotates the slider relative to the gimbal. MIMO and SIMO Controllers were Designed for cases when the microactuator's relative position error signal is respectively available and not available to the control system. The effects of MA resonance variations on the stability and performance of the Controller were analyzed for both cases.
