Fuzzy Logic Toolbox Design and simulate fuzzy logic systems Fuzzy Logic Toolbox™ provides MATLAB functions, graphical tools, and a Simulink block for analyzing, designing, and simulating systems based on fuzzy logic. The product guides you through the steps of designing fuzzy inference systems. Functions are provided for many common methods, including fuzzy clustering and adaptive neurofuzzy learning. The toolbox lets you model complex system behaviors using simple logic rules and then implement these rules in a fuzzy inference system. You can use it as a standalone fuzzy inference engine. Alternatively, you can use fuzzy inference blocks in Simulink and simulate the fuzzy systems within a comprehensive model of the entire dynamic Specialized GUIs for building fuzzy inference systems and viewing and analyzing results Membership functions for creating fuzzy inference systems Support for AND, OR, and NOT logic in user-defined rules Standard Mamdani and Sugeno-type fuzzy inference systems Automated membership function shaping through neuroadaptive and fuzzy clustering learning techniques Ability to embed a fuzzy inference system in a Simulink model Ability to generate embeddable C code or stand-alone executable fuzzy inference engines File Edit View Display Diagram Simulation Analysis Code Tools Help Target Position Target Position (Jrfo use-Driven) Carta Pole Fuzzy Logic Balancing a pole on a moving cart. The system, which is similar to an inverted pendulum, uses a Fuzzy Controller block within Simulink to balance the pole. Accelerating the pace of engineering and science

Working with the Fuzzy Logic Toolbox The Fuzzy Logic Toolbox provides GUIs to let you perform classical fuzzy system development and pattern recognition. Using the toolbox, you can: ▪ Develop and analyze fuzzy inference systems ▪ Develop adaptive neurofuzzy inference systems ▪ Perform fuzzy clustering In addition, the toolbox provides a fuzzy controller block that you can use in Simulink to model and simulate a fuzzy logic control system. From Simulink, you can generate C code for use in embedded applications that include fuzzy logic. Control System Design with SISO Design Tool 8:59 Design...

Simulating and Deploying Fuzzy Inference Systems You can evaluate FIS performance by using the Fuzzy Logic Controller block in a Simulink model of your system. The Fuzzy Logic Controller block automatically generates a hierarchical block diagram representation for most fuzzy inference systems. This representation uses only built-in Simulink blocks, enabling efficient code generation (using Simulink Coder, available separately). Fuzzy Logic Controller in Simulink 3:45 Integrate a fuzzy logic controller into a Simulink® model. You can also save your FIS in ASCII format for use outside the...
