Abstract

Highlights•A coordinated control strategy for ducted rocket regulation and protection is proposed.•The strategy ensures that the engine obtains the maximum performance while ensuring safety.•Inner/outer loop control structure decomposes the contradiction between performance and safety.•A limit protection controller design is developed utilizing a linear quadratic optimal control technique.•A hysteresis coordinated control logic is presented for thrust regulation and inlet buzz protection.
