FREELANCE ROBOTICS SERVICES
Control & Filtering
Freelance Robotics Control and Filtering ServicesFreelance Robotics provides you with tailored control system solutions.
We model the system you need to control and apply suitable control and filtering techniques to achieve the required accuracy.
If you need to control a vehicle, industrial machinery or any other device over a trajectory, Freelance Robotics can do it for you.
What is Control:Machine operation requires an understanding of both the machine and it’s environment. For this reason, control and filtering firstly models the structure and the physical environment in which it needs to adapt. Afterwards, the machine can reliably use commands and feedback to move or hold either objects or position, accounting for speed and acceleration. Notable points on the topic of control and filtering relevant to operational development are included below.
The key to effective control is the feedback of information to allow correction of initial “blind” commands. An external measurement
of the environment is taken and informs the controller of the distance from real position, and speed and acceleration needed to reach the target.
System reliability and efficiency are important measures for machine operation. This is assessed by stability and time response. Output here describes how quickly and smoothly a controller reaches either the commanded or, in case of error, the current position.
Filtering is also central to control knowledge. Filtering eliminates unwanted noise, bias or scaling factors from the feedback measurement of the environment to obtain more relevant and accurate information.
Finally, observation knowledge is a useful measure. Observation knowledge provides an estimate of the system model by observing controller behaviour and environmental feedback. In this way, the controller can be modified either in real time or later, to more accurately perform the command.
