Abstract: In order to implement the accurate and reliable ignition of MEMS (Micro Electro Mechanical Systems) solid propellant micro-thruster array，the ignition driving and control of unit array is particularly important. A driving and control system is designed and the system is composed of four modules including power module，driving module，10×10 MEMS solid propellant micro-thruster array，control and communication module. The designs of these modules are introduced. Through the integrated design，the whole structure of this system was designed and the principle prototype was manufactured. Based on the principle prototype，the electro-explosive testing，ignition testing and impulse testing are carried out. The test results indicate that the driving and control system designed for MEMS solid propellant micro-thruster array performs well. The ignition for one unit or several units can be realized. The ignition success rate is 100% and the reliability of the designed ignition driving and control system is high.
