A comprehensive set of experiments is provided with each system that graphically demonstrates important control system principals. Where competing products include only one or two controllers with each system, ECP provides a broad range of fully documented experiments and supplemental exercises. This enables you to select from the provided topics to tailor experimental activities to your specific curriculum needs.
Our experiments typically cover topics ranging from basic low order plant identification and control design to high order regulation with nonlinear compensation in MIMO systems. Detailed instructions for the students and complete solutions for the instructor greatly reduce your time in class preparation and assignment grading. Additional features such as summary review sections, Matlab® design and analysis scripts, and instructor optional assignments, let you efficiently utilize the system's broad functionality. Extensive use of graphical figures provides a concise depiction of control theory, experimental procedures, and expected results.
Experiments Common to Models 205 & 210
Many experiments are common to the Torsional and Rectilinear apparatuses as well as the other systems. These include:
- Plant Identification & Dynamic Model Building
- Rigid Body PD and PID Control
- Fundamental Open & Closed Loop Properties (second order systems, transient and frequency responses, rigid & flexible bodies, mode shapes & frequencies, time & frequency domain correlation)
- Phase & Gain Margin
- Nyquist Stability
- Root Locus Design
- Sensitivity to Parameter Changes
- Control Robustness
- Tracking Control
- Disturbance Rejection (requires secondary drive accessory)
- Tracking Control
- Flexible Structure Control (Notch filters, collocated sensor/actuator, noncollocated control, low authority / high authority loops, ploe placement, linear quadratic regulator)
- Practical Control Issues (drive saturation, sensor quantization, discrete time sampling, custom control execution)
- Any Topic You Choose! The versatility of the reconfigurable apparatus and interface software support the study of virtually any topic in control systems. The Model 205 & 210 apparatuses are particularly well suited for the study of rigid body and higher order discrete flexible systems.

- Friction
- Backlash
- Drive Flexibility
- Drive Saturation
- Sensor Quantization
- Discrete Time Sampling

The Model 750 apparatus is particularly well suited for the study of control of dynamically complex plants with global nonlinearities (its dynamics are easily reduced for study of lower order systems via the built-in motion brakes)
Advanced Experiments / Research
The control software and hardware support efficient experimentation in a wealth of areas including LQR/LTR, H-infinity, mu-synthesis, QFT, feedforward/tracking, optimal trajectory generation, system robustness , I/O system identification, and much more! In addition, by using the optional User Written Algorithm package, fully general control forms such as Fuzzy logic, Nonlinear, Adaptive, and Variable structure are readily implemented and characterized.
Dynamics & Vibrations
The Model 205 and 210 systems may be used to demonstrate a broad range of dynamics and vibrations principles using ECP's optional dynamics package. This option includes specialized software and many experiments that are complementary to control systems study. Go to Dynamics Systems /
