A control system of a motor-driven moveable platform is provided to control speed of a moveable platform. The control system of the motor-driven moveable platform includes a subtractor, a controller, and a signal converter. The subtractor produces an error speed, the controller produces a speed control signal, and the signal converter produces a speed drive signal including an accelerated drive signal and a decelerated drive signal. The accelerated drive signal and the decelerated drive signal are provided to control acceleration and deceleration of the moveable platform.

A control apparatus and the like may include a time allocation setting unit that sets a time allocation for steps in the total driving time, and an operation value calculation unit that calculates minimum operation values for the times set by the time allocation setting unit, and the time allocation setting unit sets the time allocation of the steps in the total driving time such that the difference between the minimum operation values of the steps falls within a predetermined range.

A numerical controller for performing table-format-data-based operation control includes a reading unit that analyzes a command block read from table format data to acquire a reference value and a coordinate value of a control point and outputs the reference value and the coordinate value, a segment distinction unit that divides movement to the control point into acceleration/deceleration segments and a constant speed segment, a feed speed calculation unit that calculates a feed speed in the constant speed segment, and a distribution process unit that calculates the travel of a controlled axis for each control cycle so that acceleration/deceleration is applied in the acceleration/deceleration segments and the feed speed calculated by the feed speed calculation unit is achieved, and delay in the coordinate value with respect to the reference value based on the acceleration/deceleration control is corrected by using the feed speed calculated by the feed speed calculation unit.

Methods and systems for selecting a velocity profile for controlling a robotic device are provided. An example method includes receiving via an interface a selection of a robotic device to control, and receiving via the interface a request to modify a velocity profile of the robotic device. The velocity profile may include information associated with changes in velocity of the robotic device over time. The method may further include receiving a selected velocity profile, receiving an input via the interface, and determining a velocity command based on the selected velocity profile and the input. In this manner, changes in velocity of the robotic device may be filtered according to a velocity profile selected via the interface.
