Control engineering
Achieve desired performance and stability in dynamic systems.
Our approach
We focus on practical control systems programmed into embedded microcontrollers, offering expertise in both closed and open-loop configurations.
Open-Loop Mastery:
For scenarios where real-time adjustments are unnecessary, our open-loop control systems excel. These systems follow predefined commands and algorithms, suitable for applications such as predetermined processes in manufacturing and fixed trajectory movements in automation.
A toaster activates the current flow of the coils according to a timer for a given time. Whether the bread turns crispy or not is not directly measured but assumed statistically through observation.
In most cases, this process takes 3 minutes. Usually, a potentiometer lets you adjust manually a time between 2 and 5 minutes, which can be set based on previous experiences.
- The toaster operates based on a timer, which is a one-way instruction.
- There is no feedback loop or communication regarding the actual state of the bread, making it an open-loop system.
Closed-Loop Expertise:
In the closed-loop domain, we specialize in systems that use feedback loops to adjust behavior in real-time. These systems enhance stability and accuracy by continually monitoring output and adjusting input parameters. Applications include industrial process optimization and robotics, ensuring responsive and adaptive control.
A toaster activates the current flow of the coils according to a control circuit which measures the color of the bread. The bread is known to be crispy at a given color.
The coil is supplied with current until the sensor gives feedback reporting the desired color; it then shuts down.
Compared to the previous example, the system is able to react to changes, e.g., a different flavor of bread which requires less time to toast. The previous example would've burned the bread.
Toaster states:- Heating (active control based on sensor feedback)
- Not Heating (inactive or paused state)
The control loop in this case also has two states: the heating process is active and adjusted based on sensor feedback, or it's not heating. The system transitions between these states based on the color feedback from the sensor.
Complex closed-loop systems:
In a car equipped with our advanced speed control system, the algorithms continuously assess the difference between the desired speed and the actual speed, making real-time adjustments to throttle and braking inputs.
This technology enables the vehicle to navigate varying terrains, such as uphill and downhill slopes, seamlessly adapting to changes in driving conditions and maintaining a steady speed without abrupt fluctuations.
Embedded Microcontroller Integration:
Our core competency lies in seamlessly integrating control systems into embedded microcontrollers. We navigate the complexities of hardware and software interfaces, optimizing microcontroller performance for each application. This approach ensures efficiency and reliability while minimizing physical space requirements.
Innovation and Adaptability: Remaining informed about technological advancements, we prioritize ongoing research and development. This commitment allows us to offer control systems that meet current industry standards and remain adaptable to emerging technological landscapes.
