Abstract

Sliding mode controller (SMC) has become a popular traditional control method in industries due to the most effective control strategies employing nonlinear control and the ability to reject disturbances, particularly for line trajectory control. However, this control method has chattering problems due to high-frequency switching. To cope with the shortcoming, an artificial intelligence (AI) method is utilized in the traditional SMC to eliminate or reduce this chattering problem. This paper investigates an adaptive fuzzy logic system combined with SMC algorithm to alleviate the problem. Fuzzy logic is chosen due to its advantages in tackling nonlinear properties using if-then thinking, whereas SMC method can be applied due to its ability to reject disturbance control. The inverted pendulum is selected as a controlled object and simulated using MATLAB/Simulink to investigate this control method. By combining the fuzzy logic system and the SMC approach, the chattering problems can be adaptively reduced on the line trajectory tracking signal. The adaptive fuzzy SMC achieved better performance with fast response compared with previous literature algorithms for similar plants.

Abstract

The digitalization development is accelerating, making it possible to measure the distance without touching the objects. Light detection and ranging (LiDAR) sensors are widely available on the market as components for distance measurement. Numerous studies on LiDAR sensor application have been conducted, including research on automated guided vehicle (AGV) robots, quadcopters, and tropical vegetation mappings. Previous research focused on LiDAR sensor application but did not evaluate its precision and features in depth. There are possibilities that the components’ performances do not conform with the technical data standards. This study presents the performance testing results of a TF-Mini LiDAR sensor for distance measurement. This TF-Mini LiDAR sensor testing used an experimental method. The sensor performance was determined by the maximum distance reading, accuracy level, objects’ color effect, tilt, and material type of objects being read. The testing results showed the TF-Mini LiDAR sensor had an accuracy rate of 3.17% in the range of 0.3 m to 6 m and 3.27% in the range of 6 m to 12 m, with a maximum reading distance of 10 m. Blue and iron were the most readable hue and material, with an average error rate of 2.78% and 3.2%, respectively. The distance reading results on flat objects with a tilt between 10° and 80° (quadrant 1) exceeded the actual distance as objects’ angle tilt increased, with the yielded error average of 7%. The average inaccuracy for flat objects with a tilt between 100° and 170° (quadrant 2) was 2.75%. Additionally, the distance reading accuracy improved as the objects’ degree of tilt increased. Based on the testing results, the TF-Mini LiDAR sensor could measure distances more precisely when the detected item was between 0.5 m and 10 m away, has a non-light-absorbing color and material, and is in the straight state.
