Feedback control system for cryogenic mapping and cryogenic ablation

Methods and systems for feedback control for cryogenic mapping and cryogenic ablation are disclosed. According to one aspect, a cryogenic mapping and cryogenic ablation control system includes a first control device configured to receive a target parameter value and a measured output parameter, and output an injection pressure target signal based on a first difference between the target parameter value and the measured output parameter. The system also includes a second control device configured to receive the injection pressure target signal and output a valve control signal for setting a position of an injection pressure valve. The first control device is configured to determine a value of the injection pressure target signal to tend the first difference to zero. 公开了用于低温标测和低温消融的反馈控制的方法和系统。根据一个方面，低温标测和低温消融控制系统包括第一控制装置，该第一控制装置被配置为接收目标参数值和测量输出参数，并且基于该目标参数值与该测量输出参数之间的第一差值输出注射压力目标信号。该系统还包括第二控制装置，该第二控制装置被配置为接收该注射压力目标信号并且输出阀控制信号，该阀控制信号用于设定注射压力阀的位置。该第一控制装置被配置为确定该注射压力目标信号的值以使该第一差值趋向于零。
