“…In this section different control system algorithms for US-guided minimally invasive robotic surgery platforms are discussed. Most notable of the main control algorithms include: position based visual servo control algorithms (PBVS) [51], [55]- [64], [95], [99], [102]- [103], image based visual servo control algorithms (IBVS) [41], [66]- [67], [78], [85]- [90], [96], [100], nonlinear model predictive control [91], motion compensation control for involuntary rhythmic motions (e.g. heartbeat) which often consists of feed-forward Coulomb friction model compensation and backlash inverse compensation [13], [68]- [72], force control algorithms [72], and virtual RCM control algorithm [74], [76].…”
