A highly interpretable fuzzy rule base using ordinal structure for obstacle avoidance of mobile robot

Conventional fuzzy logic controller is applicable when there are only two fuzzy inputs with usually one output. Complexity increases when there are more than one inputs and outputs making the system unrealizable. The ordinal structure model of fuzzy reasoning has an advantage of managing high-dimens...
