Single-gimbal control moment gyroscopes (CMG) offer significantly greater vehicle acceleration (>100x) than a reaction wheel system of the same power. However, controlling an array of CMGs is a difficult task. Honeywell has developed turnkey controls for “roof” arrays of up to six CMGs that can be embedded in the array hardware or licensed separately. These controls accept a simple torque command, and provide deterministic, singularity-free operation with guaranteed torque availability. They also transparently manage CMG hardware failures, spin-up/down events, etc. without loss of control.
