Lin 等人提出的用于实现组织控制方法 (TCM) 的模糊控制器。 （《Physol Meas》，2006 年）提出了测量瞬时动脉血压的方法。 TCM 采用压电执行器上下移动压力传感器，通过跟踪血压的变化来维持在皮肤上测量的平均血压。由于压电执行器的操作在执行器运动中表现出滞后行为，因此控制器应该能够跟踪血压变化并补偿滞后运动。采用 Takagi-Sugeno 模糊模型来代表 Bouc-Wen 模型，用从执行器的动态响应中确定的参数来描述迟滞。在该模型的基础上，开发了稳定的模糊观测器来线性化压电执行器的运动，并设计了 PI 控制器来跟踪血压的变化。所设计的模糊控制器在软硬件测试中成功跟踪了各种指令信号。模糊控制器位于测量瞬时血压的仪器中。实验结果表明，所提出的模糊控制器对于压电陶瓷执行器的控制是可行且令人满意的。
A fuzzy controller to implement tissue control method (TCM) proposed by Lin et al. (in physiol Meas, 2006) to measure the instantaneous arterial blood pressure is presented. The TCM adopts a piezo-actuator to move the pressure transducer up and down to maintain the mean blood pressure measured on the skin by tracking the variation in the blood pressure. Since the operation of the piezo-actuator exhibits hysteresis behaviour in the actuator movement, the controller should have the ability to track the blood pressure variation as well as compensate for the hysteretic movement. A Takagi-Sugeno fuzzy model is adopted to represent the Bouc-Wen model in describing the hysteresis with parameters identified from the dynamic responses of the actuator. On the basis of the model, a stable fuzzy observer is developed to linearise the movement of the piezo-actuator, and a PI controller is designed to track the variation in blood pressure. The designed fuzzy controller has successfully tracked various command signals during software and hardware tests. The fuzzy controller is located in an instrument that measures the instantaneous blood pressure. The experimental results show that the proposed fuzzy controller is feasible and satisfactory for controlling the piezo-actuator.
