Electrically controlled solid propellant （ECSP） has the characteristics of multiple ignitions and controllable burning rate， and can be widely used in propulsion systems from micro to macro. The research on ECSP with ammonium nitrate， hydroxylamine nitrate and perchlorate as oxidants was summarized at home and abroad， especially the characteristics of ignition， combustion and extinction for ECSP based on hydroxylamine nitrate and perchlorate were emphatically reviewed. Meanwhile， the effects of voltage， pressure and metal additives on the burning rate adjustment of ECSP were analyzed， and the mechanism of electric energy in the ignition and combustion process of ECSP was discussed. Furthermore， some suggestions were put forward for further in-depth study on the ignition， combustion and extinction mechanism of ECSP： study the chemical reaction mechanism on the solid and gas phases of ECSP， establish the model and framework of the reaction mechanism for ignition， combustion and extinction； explore the effect of electrode arrangement and electrode configuration on the combustion efficiency of ECSP and the relationship between ECSP formula and electrical conductivity systematically， and seek the method to decrease the interface resistance between electrode and propellant. Finally， optimizing the formulation of high-performance ECSP， perfecting the combustion reaction mechanism and burning rate adjustment mechanism of ECSP， and raising the pressure threshold of ECSP are the keys to the design， application and performance regulation of electronically controlled solid rocket motor.
