  We study and analyze the dynamic properties of both canonical and
noncanonical warm inflationary models with dissipative effects. We consider
different models of canonical warm inflation with different dissipative
coefficients and prove that the behavior at infinity of quadratic dissipative
model distinctly differs from that of the constant dissipative model, which
means that quadratic dissipative coefficient increases the possibility of the
occurrence of inflation. We also show that the different choice of combination
of the parameters in noncanonical warm inflation exhibits dramatically
different global phase portraits on the Poincar\'{e} disk. We try to illustrate
that the noncanonical field will not expand the regime of inflation, but it
will increase the possibility of the occurrence of inflation as well and the
duration of inflation. Then, by dynamic analysis, we can exclude several
inflationary models, like the warm inflation model, with negative dissipative
coefficients, and explain that the model without potential is almost
impossible. With relevant results, we give the condition when reheating occurs.
