The paper discusses feedback control of an important class of plasma instabilities consisting of drift waves, some flutes, and trapped particle modes. These instabilities, which have discrete spectra involving a reasonable number of modes, are for all practical purposes shown to be completely observable and controllable with a single internal sensor and single suppressor. The paper develops detailed stabilizing feedback controllers for a multimode collisional drift wave instability in a Q-machine and for a dissipative trapped electron mode in a linear machine.
