Definitions
- the motor is part of a controlled mechanical system.
- the complete system includes a module that provides iterative real-time process control, which accepts as one input a position, such as a motor shaft position and outputs a desired motor acceleration, or torque. This desired acceleration goes to the linearization module, which then drives the motor in the system.
- a position such as a motor shaft position
- a desired motor acceleration or torque
- the linearization module which then drives the motor in the system.
- the iterative real-time process control also accepts a goal stream, such as a sequence of waypoints.
- Each waypoint may comprise both a target position and target velocity of the motor.
- multiple iterations are used to achieve the target waypoint.
- Fig. 1 shows an embodiment of a closed-loop system with a linearization module.
- Fig. 2 shows another embodiment of a closed-loop system with non-linear forcing function.
- the iterative, real-time process control module 13 has to know what the goal of the operating system is. Typically, it accepts a series or stream of waypoints, 19. In some embodiments, each waypoint includes both a target position and target velocity. Typically, multiple iterations of the closed-loop system will be used to achieve each target waypoint.
- Claim 3 at least one purpose and construction of the table(s) is to linearize drive to the motor such that the motor actually implements the desired acceleration, or an acceleration (or torque) that is linear with the desired acceleration.
- Acceleration as either an input or output of the table, may be normalized, such as from -1 to +1 where this range corresponds to the maximum possible negative acceleration (slowing or accelerating backwards) and to the maximum possible positive acceleration.
- Velocity for the iterative jerk method, and for a motor controller, velocity is a scalar per axis that is position per unit time. An alternative word is rate. In the context of core methods and devices, velocity does not include a heading vector because it applies to a single axis. Velocity is typically signed, but may not be. The sign, or direction, may be implied. See also note on term usage.
