(d) Statement 1: Next-generation motion systems are inherently multi-variable since the flexible dynamical behaviour is generally not aligned with the motion DOFs. Statement I is Correct. In advanced motion systems, flexible structures (e.g., robotic arms, precision platforms) exhibit dynamics that cannot be controlled independently along their degrees of freedom (DOFs). This leads to multi-variable behavior, requiring advanced control strategies. Statement 2: Next-generation motion systems are envisaged to be designed with many actuators and sensors to actively control flexible dynamic behaviour, whereas traditionally, the number of inputs and outputs equals the number of motion DOFs. Statement 2 is Correct. Traditional systems often match number of actuators = number of DOFs, but next-gen systems introduce redundant actuators and sensors to control flexible modes, vibrations, or enhance precision - a key feature in mechatronics and robotics. Statement 3: A model-based design provides a systematic control design procedure for multivariable systems. Statement 3 is Correct. Model-Based Design (MBD) uses mathematical models (e.g., statespace, transfer functions) to develop and validate control systems, especially for multi-input, multi-output (MIMO) systems. It is widely adopted in next-generation motion control.
