Shape memory alloys (SMA’s) are inherently nonlinear devices exhibiting significant hysteresis in their stressstrain-temperature characteristic. As a consequence most SMA actuator systems presented in the literature employ some form of proportional-integral-derivative (PID) or pulse-width modulated (PWM) control. Unfortunately, due to the hysteresis of the(More)
This paper presents a systematic procedure for constructing a multi-input multi-output fuzzy controller that guarantees identical performance to an existing stabilizing linear controller. An algorithm is devised that generates a fuzzy controller which is functionally identical to a given time-invariant or time-varying finite-dimensional linear controller.(More)
