Abstract: Reconfigurable computing has grown to become an important and wide field of research. Broadly considered, reconfigurable devices fill their silicon area with a larger number of computing primitives, interconnected via a configurable network. The operation of each primitive can be programmed, as well as the interconnect pattern, computation tasks can be implemented spatially on the device directly from the producing function to the receiving function. 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 application from software-hardware solution using FPGAs. The parallel structures or repetitive loops in control system design can be broken into multiple data paths and processed in parallel routine in an FPGA in order to increase the processing speed of the system. This dissertation investigates an FPGA-based PID controller for Hard Disk Drive read/write system. An attempt has been made to design and simulate a feedback control system using FPGA for optimal performance. Ultimately the optimally controlled movement of Hard Disk Drive read/write head has been achieved. Improvements have been seen in simulating the system design on ModelSim as the overshoot in the FPGA design is zero percent, a very fast response to a step input giving the rise time of 0.1806μs and the settling-time has been reduced to 0.3234μs. The results of hard disk drive read/write system are very encouraging to design and simulate the higher order systems onto the FPGA systems
