Abstract
In accordance with one embodiment of the invention a control system for controlling performance of a device is provided. The control system includes a controller system and a deadband compensator connected to the controller. The deadband compensator compensates for error performance of the device while the device is in a static mode. The control system also includes a detector connected to the controller and is adapted to detect or determine movement of the device. If movement is detected or determined the deadband compensator is turned off or otherwise disengaged.
Claims13
A control system for controlling performance of a device, the control system comprising:
- a controller system;
- a first deadband compensator connectable to the controller system, the first deadband compensator compensating for error performance of the device;
- and
- a first detector connected to the controller system, wherein the first detector is adapted to detect a point command of the device and wherein the first deadband compensator connects to the controller system to position the device in a predetermined deadband zone when the first detector does not detect a point command, and wherein the first deadband compensator disconnects when the first detector detects a point command.
A method for deadband control in a control system, the method comprising:
- determining a deadband zone error term;
- determining a point command;
- and
- engaging a deadband controller responsive to determining the deadband zone error term and the point command.
An integrated circuit (IC), wherein the IC comprises:
- a controller system;
- a first deadband compensator connected to the controller, the first deadband compensator compensating for error performance of the device;
- and
- a first detector connected to the controller, wherein the first detector is adapted to detect movement of the device.
A program storage device readable by a machine, tangibly embodying a program of instructions executable by the machine to perform method steps for deadband control in a control system, the method comprising:
- determining a deadband zone error term;
- determining a point command;
- and
- engaging a deadband controller responsive to determining the deadband zone error term and the point command.
