The middeck active control experiment (MACE) was designed as a Space S
huttle flight experiment to demonstrate high authority active structur
al control in zero-gravity (0-g) conditions based on analysis, ground
testing, and on-orbit control redesign. MACE is a multidisciplinary pr
oject that is at the forefront of flexible structural control. MACE wa
s first flown on STS-67 in March 1995, and a summary of the program ob
jectives and mission experimental results is provided.
