Designing a controller that balances two links adds an extra challenge when compared to the single inverted pendulum system. The additional challenge of a second pendulum can be used to demonstrate advanced controls concepts, or as a basis for research.
Linear Double Inverted Pendulum
The double inverted pendulum represents a complex challenge with real-world applications that include stabilizing the takeoff of a multi-stage rocket and modeling the human posture system.

QLabs Robotics
QLabs Robotics is a collection of virtual laboratory activities that supplement traditional or online robotics courses. The virtual hardware labs are based on Quanser QArm robotic manipulator and QBot 2e mobile ground robot. The virtual twins of these robots are fully instrumented and dynamically accurate, allowing users to measure simulated sensors, including video and depth data, interact with virtual environments, and work with the same code created for the "real" robots. With QLabs Robotics, you can combine physical and virtual plants to enrich your lectures and in-lab activities and increases engagement and students’ learning outcomes in class-based or online courses.
Coupled Tanks
Designed in association with Prof. Karl Åström and Prof. Karl Henrik Johansson, the Coupled Tanks system consists of a single pump with two tanks. Each tank is instrumented with a pressure sensor to measure the water level. The pump drives the water from the bottom basin up to the top of the system. Depending on how the outflow valves are configured, the water then flows to the top tank, bottom tank, or both. The rate of flow can also be changed using outflow orifices with different diameters. The ability to direct water flow, together with variable outflow orifices allows for several interesting Single Input Single Output (SISO) configurations. Further, two or more Coupled Tanks can be combined together for Multiple Input Multiple Output (MIMO) experiments.
QLabs Virtual Rotary Servo
Same as the physical Rotary Servo Base Unit, the virtual system features a DC motor that drives a smaller pinion gear. This gear is fixed to a larger middle gear that rotates on the load shaft. The position of the load shaft is measured using a high-resolution optical encoder or a potentiometer.
Linear Flexible Joint with Inverted Pendulum
The Linear Flexible Joint with Inverted Pendulum combines two fundamental control challenges to give students an opportunity to a more advanced modeling and control challenge.
QLabs Controls
QLabs Controls is a collection of virtual laboratory activities that supplement traditional or online control systems courses. The virtual hardware labs are based on Quanser QUBE-Servo 2 and Quanser AERO systems which allows you to combine physical and virtual plants to enrich lectures and in-lab activities and increases engagement and students’ learning outcomes in class-based or online courses.
Linear Flexible Inverted Pendulum
The linear flexible inverted pendulum challenges students to gain advanced modeling and control experience by controlling both the damping of a flexible link, and an unstable inverted pendulum.
Linear Flexible Joint
The Linear Flexible Joint experiment will help your students learn how to model and control real-world dynamic systems such as flexible couplings and gearboxes.
QLabs Virtual QUBE-Servo 2
Same as the physical QUBE-Servo 2, the virtual system features a DC motor with the inertia disk and inverted pendulum modules. Rotary encoders measure the angular position of the DC motor and pendulum. The motor angular velocity is measured through a software-based tachometer.
