Dual control architecture for hydraulic and electric brake systems

An aircraft, comprising:

• a wheel;
• and
• a brake system coupled to the wheel, wherein the brake system comprises:
• a brake mode selection mechanism configured to provide a desired braking command;
• an antiskid control mechanism configured to provide an antiskid control braking command;
• a desired braking controller;
• an antiskid controller;
• and
• a brake executive mechanism configured to:
• determine whether the antiskid control braking command is less than the desired braking command;
• responsive to the antiskid control braking command being less than the desired braking command, send a first command to implement the antiskid control braking command, wherein responsive to receiving the first command, the antiskid controller is configured to control at least one of a pressure or a force applied to a brake assembly;
• and
• responsive to the desired braking command being less than the antiskid control braking command, send a second command to implement the desired braking command, wherein responsive to receiving the second command, the desired braking controller is configured to control at least one of the pressure or the force applied to the brake assembly.

A method for dual control of a brake system, the method comprising:

• receiving, by a brake executive mechanism via a brake mode selection mechanism, a desired braking command;
• receiving, by the brake executive mechanism via an antiskid control mechanism, an antiskid control braking command;
• determining, by the brake executive mechanism, whether the antiskid control braking command is less than the desired braking command;
• responsive to the antiskid control braking command being less than the desired braking command, sending, by the brake executive mechanism, a first command to implement the antiskid control braking command, wherein the first command causes an antiskid controller to control at least one of a pressure or a force applied to a brake assembly;
• and
• responsive to the desired braking command being less than the antiskid control braking command, sending, by the brake executive mechanism, a second command to implement the desired braking command, wherein the second command causes a desired braking controller to control at least one of the pressure or the force applied to the brake assembly.
