● SISO Magnetic Levitation Control Experiments
Magnetic levitation (maglev) technology is a fascinating application of control engineering where an object is suspended in space using magnetic forces, counteracting gravitational pull. These systems demonstrate the principles of electromagnetic force control, feedback mechanisms, and stability analysis, making them valuable for both educational and research purposes. In the context of control systems, Single-Input Single-Output (SISO) magnetic levitation systems focus on controlling a single parameter, such as the vertical position of a levitating object, using a single control input — typically the current through an electromagnet. The objective is to achieve stable levitation by maintaining the object’s position at a desired setpoint while minimizing oscillations or disturbances.
SIMO Digital Inverted Pendulum
The inverted pendulum is a classic example in control engineering that illustrates the challenge of stabilizing an inherently unstable system. When extended to a Single-Input, Multiple-Output (SIMO) configuration, the problem becomes even more intriguing and complex, making it a popular choice for research, education, and real-world applications. In a SIMO digital inverted pendulum system, there is a single control input — usually a motor torque or force applied to a cart — while there are multiple outputs to be controlled, such as the cart’s position and the pendulum’s angle. The primary goal is to keep the pendulum balanced in its unstable upright position while possibly regulating the cart’s position on a track.
MIMO Twin rotor system
The Multiple-Input Multiple-Output (MIMO) Twin Rotor System (TRS) is a popular experimental setup used in control engineering to study complex, coupled dynamic systems. It is inspired by the behavior of helicopters and quadcopters, making it a valuable testbed for exploring advanced control strategies. The system typically consists of a two-bladed rotor assembly mounted on a pivot. The two rotors — a main rotor for vertical movement and a tail rotor for horizontal movement — control the system’s elevation and azimuth angles. These two control inputs affect both angles simultaneously due to the strong coupling between them, leading to a highly nonlinear, multivariable system.
