ABSTRACT = {Detumbling	is	a	crucial	first	step	for	on-orbit	service	and	space	debris	removal.	Plume	is	an	efficient	medium	
for	 failed	 spacecraft	 detumbling	 which	 can	 avoid	 direct	 contact	 to	 ensure	 the	 safety	 of	 the	 spacecraft.	
However,	traditional	molecular	plume	may	lead	to	an	unaffordable	fuel	consumption.	This	paper	proposes	
a	 novel	 detumbling	 strategy	 by	 using	 plasma	 plume	 with	 the	 popularization	 of	 Hall	 effect	 thrusters	 on	
spacecraft.	To	overcome	the	difficulty	of	real-time	calculation	in	traditional	models,	a	fully	analytical	plasma	
plume	 model	 is	 established	 which	 can	 improve	 the	 autonomy	 of	 the	 chaser[1].	 An	 optimal	 detumbling	
guidance	law	is	proposed	to	mitigate	the	spin	angular	velocity	while	stabilizing	the	nutation	by	adjusting	the	
direction	of	the	plasma	plume	and	the	position	of	the	chaser	in	real	time[2].		In	order	to	improve	the	control	
efficiency	of	 the	chaser,	a	prescribed	performance	 framework	is	established	and	a	 terminal	non-singular	
sliding	mode	controller	(TSM)	is	designed	in	this	framework[3].	This	adaptive	controller	is	used	to	track	the	
time-varying	 desired	 chaser	 position	 to	 realize	 closed	 loop	 control.	 Numerical	 results	 indicate	 that	 the	
proposed	 plasma	 plume	 model	 can	 significantly	 improve	 the	 computational	 efficiency	 and	 the	 optimal	
guidance	law	can	stabilize	the	target	within	an	acceptable	time.	Compared	with	traditional	control	methods,	
TSM	 controller	 shows	 better	 stability	 and	 faster	 convergence	 under	 nonlinear	 disturbance.	 This	 study	
provides	important	technological	supports	for	autonomous spacecraft	detumbling.},
