This classical system appears commonly in dynamics and controls text books and serves as a benchmark for control method evaluation. Its dynamic properties are generally the rectilinear equivalent of those of the Torsional Apparatus with additional parameter adjustment capability.
As with Model 205, this system provides vivid demonstrations of elementary topics such as rigid body PID control, lead/lag compensators, phase and gain margin, trajectory tracking, and regulation - as well as advanced high order collocated and noncollocated system control. The two apparatuses also clearly demonstrate salient properties of flexible systems such as mode shapes, natural frequencies, and characteristic transient and frequency responses. An optional secondary drive may be positioned at any output (mass carriage) to create a MIMO plant (requires Executive USR™ software) and provide for the study of disturbance rejection.
