A servomechanism controller for controlling the movement and positioning of a servomechanism (such as that of an actuator assembly for the read/write heads of a hard disk drive assembly) in accordance with an improved “bang-bang”seek technique includes at least one neural network. In one embodiment, a single neural network, connected to a plant with servomechanism, receives two input positioning signals and provides an output positioning signal. One input positioning signal represents a desired servomechanism position, while the other represents its present position. The output positioning signal represents a positioning time period within which the servomechanism will reach the desired position plus a deceleration time period within the positioning time period upon the termination of which the servomechanism will reach its desired position. In another embodiment, one neural network, connected to the plant, receives an input positioning signal and provides an output positioning signal and a status signal. The input positioning signal represents a desired servomechanism position. The output positioning signal represents a positioning time period within which the servomechanism will reach its desired position. The status signal represents a control status of the neural network. Another neural network, also connected to the plant, receives the status signal plus a feedback signal and provides a correction signal. The feedback signal represents the present servomechanism position, while the correction signal represents a deceleration time period within the positioning time period upon the termination of which the servomechanism reaches its desired position.
