Simultaneous feedforward online command rate limiter filters for existing controllers

One of the biggest challenges in controller design for a mechatronics system is actuator limitations. Either response time or input constraints creates limits performance and stability. In this study novel feedforward online rate limiter scheme arbitrary signals introduced by taking velocity, acceleration jerk into account, it investigated that how control effort affected demand signal's change A fin actuation guided missile given as an example where signal comes from guidance online. Different limiting schemes are reviewed, simulations carried out comparison. Proposed method shown to be effective via simulation confirmed experimental results existing controller.
