Design Reliable Control Systems Validated on Realistic Mechanism Models

Today, many mechanical systems are driven by control systems, hydraulics or pneumatics. Cars and airplanes contain numerous control systems and the use of hydraulics and pneumatics is common practice in construction machinery and manufacturing equipment. Assessing the coupled behavior of controls and mechanics is the major challenge when designing such mechatronic systems. LMS Virtual.Lab Motion allows engineers to define and optimize the control strategy on the virtual prototype.

Designing reliable controls …

At the beginning of the control design process, LMS Virtual.Lab Motion assists the engineer by linearizing the mechanism that needs to be controlled. Applying automatic linearization saves time and avoids errors. Once a control design is available, the controller can be tested on the full non-linear virtual prototype. The complete motion range of the controlled mechanism can then be thoroughly simulated, while taking into account gravity, friction, material elasticity and other physical phenomena.

.… in the most efficient way

Connecting the mechanism with the control scheme only takes seconds. In Matlab/Simulink or Easy5, LMS Virtual.Lab Motion creates a simple building block, which represents the mechanics of the system and all inputs and outputs. During coupled simulations, control and mechanism equations are both solved while sensor outputs and actuator inputs are automatically exchanged. Such advanced simulations offer accurate and reliable insights that could never be obtained with any separate control or mechanism model.
