Design and Implementation of a Hard Disk Drive Read/Write Head Controller Using FPGA for Optimal Performance

Abstract

Many automatic control systems utilize digital control algorithms for the control of desired plant. Fast processing in recent microelectronics components and flexibility inherent for all these programmable solutions gave favor to digital control applications from software-hardware solutions using FPGA. This paper investigates an FPGA-based PID control system for Hard Disk Drive read/write system. An attempt has been made to design and implement a feedback control system using FPGA for optimal performance. Ultimately, the optimally controlled movements of Hard Disk Drive read / write head has been achieved
