Abstract: A Microcomputer Control System(MCS) applied to the Throttling Liquid Rocket Engine(TLRE) is presented in this paper,and the superiorly is discussed.The MCS was designed and developed and more than twenty test firings were conducted to verify the feasibility and rationality of the MCS.The test results has shown that the non-linear control method and adaptive gain technique can be conveniently realized by using the ability of the MCS,which can greatly improve the transient response performance and the static accuracy of the TLRE as compared with the previous anolog circuitry controller.In addition,the MCS has also been used in test data acquaisition and processing during the tests,so that the relevant performance parameters of the TLRE can be promptly provided in the form of table and graph,which resultes in a high efficiency and a shorter time for. the test preparation.
