ABSTRACT:
A voltage mode drive for a servo system builds a drive matrix from an error signal, which is the difference between a measured value for a parameter of the servo system, such as the position of a rotating drum, and a reference signal, a voltage control signal for the servo system, and an estimated set of parameters for the servo system, the parameters including drive current. The outputs from the drive matrix are a new estimated set of parameters for the servo system which are multiplied by appropriate system constants to produce the voltage control signal. The voltage control signal is amplified by a voltage amplifier and applied to drive the servo system.
