Research on Vibration Reduction Control Based on Reinforcement Learning

Table 4

The result of MR damper vibration reduction under different reward evaluation functions.

Observation index	Reward evaluation function
	Displacement	Speed	Acceleration
Maximum displacement response (mm)	0.044 (45.13%)	0.044 (45.63)	0.056 (29.50%)
Maximum speed response (mm/s)	2.308 (47.21%)	2.286 (47.73%)	2.876 (34.24%)
Maximum acceleration response(m/s^2)	0.123 (47.62%)	0.122 (48.17%)	0.179 (24.00%)
Maximum damping force (N)	7064	7063	9903

Note. The value in parentheses is the response reduction rate, that is (no control situation−control situation)/no control situation.
