Simulation of a Floppy Disk Drive Head Position Controller
A floppy disk drive head positioning controller system is employed to demonstrate the Saber simulator’s capabilities in mixed analog-digital and mixed technology design. The models used to represent the various components of the system are described. Issues such as hierarchical modeling, mixed signal modeling, model re-use, and modeling of the interfaces between analog and digital as well as that between the electrical and mechanical are addressed. System level responses such as the read/write head position settling time, step loss of the stepper motor, and mechanical loading effects are demonstrated.
