Current position number S2=1, position number of rotation graduation S1=12,RNO=1,DIR=1 POS=1,INC=0: When S3=10 goal position is A, and ACT=1, S4=11,W=1. When S3=8 goal position is B, and ACT=1, S4=9,W=1. When S3=5 goal position is C, and ACT=1, S4=4,W=0. 35 ...
All parameters are reported as percentages and mean ±SEM. Differences between groups were analyzed using the Fisher's exact test for qualitative variables. The Shapiro-Wilk test was used to check the normality of data distribution. The Student's t-test was used when data were normally ...
Sun et al. [17] first generated an initial feedrate curve, and then adjusted the feedrate for the sample points on that curve that did not satisfy the constraint by using an iterative approach until the feedrate of all sample points met the constraint. The above point-by-point planning ...
2.2. Second Experiment (Scenario)—Modified Static Stiffness Measurement across All Positions When applying load to positions on the table, the work procedure will involve alternating load and load‐free cycles. The reason for...

The proposed approach contained a system identification phase and a servo tuning phase based on the same bandwidth for all axes feed drive systems. The PSO algorithm was adopted to obtain the system parameters and maximize the corresponding bandwidth. An efficient two-step servo tuning method based...
