Redundancy control can effectively enhance the stability and robustness of a system. Based on the conventional redundancy control switchover and majority arbitration strategy, this paper introduces the concept of heterogeneity and dynamics, constructs a dynamic heterogeneous redundancy-based microcontroller architecture DHR-MCU, and designs a fixed-leader distributed consensus algorithm that satisfies the program running state control of this architecture. The theoretical analysis and actual measurement of the prototype system prove that this architecture has good anti-attack and self-recovery capabilities under normal functions and performances and meets the general robust features in terms of safety and security.
