Hi, I've only been using Matlab for a week or so at Uni, so am a complete newbie. As part of my coursework I must create a PID closed-loop control system. The problem I have is; as part of a feedback loop to be created in simulink, the given circuit shows a block with the value (0.5). I've tried using (constant), but get red wires. It needs to have an input wire & output wire. What block should I be using?
MATLAB: Matlab, Simulink, which block
MATLABsimulinkwhich block?
