Simulink Control System
(OP)
Just new at Simulink. Got two questions. Thanks a lot for help.
1) control logic of U in PID is based on
Delta U = Kp *e , i.e. U(i) = U(i-1) + Kp *e(i)
How to realize it based on U? Currently just used a delay and sum to add U(i-1) into PID calculation
2) when state space model is used, I must need to linearize around steady state. How can I keep all the information such as U rather than DeltaU around stready state?
dT/dx = A* (T-T0) + B(U-U0). Basically how can I input To and U0 as constant in model?
