Truth Tables

Represent combinational logic for decision-making applications

Truth table functions implement combinatorial logic design in a concise, tabular format. Include a truth table inside a Stateflow^®chart or add aTruth Tableblock directly to your Simulink^®model.

Home Climate Control Using the Truth Table Block

Models a home climate control system by using a Truth Table block. Homes rarely maintain a constant climate without a climate control system in place, and occupants usually rely on automated systems to maintain a desired climate. Because temperature and humidity are dynamic, maintaining desired conditions requires consistent monitoring and adjusting. To model how a home activates different subsystems that maintain a desired climate, this model uses a Truth Table block to manage logical decision making.

Detect Faults in Aircraft Elevator Control System

Design a fault detection, isolation, and recovery (FDIR) application for a pair of aircraft elevators controlled by redundant actuators. This model uses the same fault detection control logic as the Avionics subsystem of the Aerospace Blockset™ example HL-20 Project with Optional FlightGear Interface (Aerospace Blockset).
