Abstract
A method for controlling a braking operation applied to a wheel of a wheel assembly includes receiving a command signal in proportion to an amount of braking requested at an input device; outputting a control signal in proportion to the command signal; receiving a wheel speed signal indicative of a speed of the wheel; calculating an adjustment signal in proportion to the wheel speed signal; providing a modified control signal to a brake actuator based on the control signal and the adjustment signal; and continually resetting a reset schedule based on the wheel speed signal.
Claims20
A brake control system for controlling a braking operation applied to a wheel of a wheel assembly, comprising:
- a brake control unit configured to output a control signal to a Proportional Integral Derivative (PID) controller;
- the PID controller in communication with the brake control unit, the PID controller configured to receive the control signal from the brake control unit and an adjustment signal from an antiskid brake controller and output a modified control signal;
- a wheel speed sensor configured to output a wheel speed signal indicative of a speed of the wheel to the antiskid brake controller;
- and
- the antiskid brake controller in communication with the PID controller and with the wheel speed sensor, the antiskid brake controller configured to receive the wheel speed signal from the wheel speed sensor and to provide the adjustment signal to the PID controller;
- wherein the antiskid brake controller provides the adjustment signal to the PID controller in proportion to the wheel speed signal;
- wherein the modified control signal is adjusted based on the control signal and the adjustment signal;
- and
- wherein a reset schedule of an integrator of the PID controller is continually reset based on the wheel speed signal, and wherein a margin of the reset schedule is varied in proportion to the speed of the wheel.
A method for controlling a braking operation applied to a wheel of a wheel assembly, comprising:
- receiving a command signal in proportion to an amount of braking requested at an input device;
- outputting a control signal in proportion to the command signal;
- receiving a wheel speed signal indicative of a speed of the wheel;
- calculating an adjustment signal in proportion to the wheel speed signal;
- providing a modified control signal to a brake actuator based on the control signal and the adjustment signal;
- and
- continually resetting a reset schedule based on the wheel speed signal, wherein a margin of the reset schedule is varied in proportion to the speed of the wheel.
A brake control system for controlling a braking operation applied to a wheel of a wheel assembly, comprising:
- a non-transitory memory configured to store instructions;
- and
- one or more processors in electronic communication with the non-transitory memory, the one or more processors configured to:
- receive a command signal in proportion to an amount of braking requested at an input device;
- output a control signal in proportion to the command signal;
- receive a wheel speed signal indicative of a speed of the wheel;
- calculate an adjustment signal in proportion to the wheel speed signal;
- provide a modified control signal to a brake actuator based on the control signal and the adjustment signal;
- and
- continually reset a reset schedule based on the wheel speed signal, wherein a margin of the reset schedule is varied in proportion to the speed of the wheel.
