We study the optimal control problem of system governed by retarded functional differential $$ x^{'}(t)= A_0x(t)+ A_1x(t-h)+ \int_{-h}^0 a(s)A_2x(t+s)ds + B_0u(t) $$ in Hilbert space $H$. After the fundamental facts of retarded system and the description of condition so called a weak backward uniqueness property are established, the technically important maximal principle and the bang-bang principle are given. its corresponding linear system.
Keywords: optimal control problem, retarded functional differential equation, maximal principle, bang-bang principle
