# A Fault-Tolerant Controller for an SP-100 Space Nuclear Reactor

### Ju Hyun Kim, Dae Seup Kim, Man Gyun Na

#### Abstract

The control system is a key element of space reactor design to meet the space mission requirements of safety, reliability, survivability, economics, and autonomous action. The objectives of the proposed model predictive control are to minimize both the difference between the predicted TE power and the desired power, and the variation of control drum angle that adjusts the control reactivity. A genetic algorithm is used to optimize the model predictive controller. The model predictive controller is integrated with a fault detection and diagnostics algorithm so that the controller can work properly even under input and output measurement faults. Simulation results of the proposed controller show that the TE generator power level controlled by the proposed controller could track the target power level effectively even under measurement faults, satisfying all control constraints.
