A Low-Cost Inverted Pendulum System for Control System Education

Abstract A low-cost inverted pendulum system for educational purpose is introduced. This system is low-cost (21,000 Yens) and simple (only angle sensor is used). The controller is a second order unstable controller with one unstable pole. A design approach called as coefficient diagram method is used in design. The effectiveness of this approach is fully demonstrated by easiness of design, simplicity of the designed controller, and the robustness of the system.
